CVE-2025-299120.02—0.21Mar 17, 2025CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. In versions 1.3.3 and prior, an unsigned integer underflow in the `Crypto_TC_ProcessSecurity` function of CryptoLib leads to a heap buffer overflow. The vulnerability is triggered when the `fl` (frame length) field in a Telecommand (TC) packet is set to 0. This underflow causes the frame length to be interpreted as 65535, resulting in out-of-bounds memory access. This critical vulnerability can be exploited to cause a denial of service (DoS) or potentially achieve remote code execution. Users of CryptoLib are advised to apply the recommended patch or avoid processing untrusted TC packets until a fix is available.
CVE-2025-302160.01—0.08Mar 25, 2025CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. In versions 1.3.3 and prior, a Heap Overflow vulnerability occurs in the `Crypto_TM_ProcessSecurity` function (`crypto_tm.c:1735:8`). When processing the Secondary Header Length of a TM protocol packet, if the Secondary Header Length exceeds the packet's total length, a heap overflow is triggered during the memcpy operation that copies packet data into the dynamically allocated buffer `p_new_dec_frame`. This allows an attacker to overwrite adjacent heap memory, potentially leading to arbitrary code execution or system instability. A patch is available at commit 810fd66d592c883125272fef123c3240db2f170f.
CVE-2025-299090.01—0.16Mar 17, 2025CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. In versions 1.3.3 and prior, a heap buffer overflow vulnerability in CryptoLib's `Crypto_TC_ApplySecurity()` allows an attacker to craft a malicious TC frame that causes out-of-bounds memory writes. This can result in denial of service (DoS) or, under certain conditions, remote code execution (RCE). Any application or system that relies on CryptoLib for Telecommand (TC) processing and does not strictly validate incoming TC frames is at risk. This includes satellite ground stations or mission control software where attackers can inject malformed frames. A patch is available at commit c7e8a8745ff4b5e9bd7e500e91358e86d5abedcc.
CVE-2026-226970.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, CryptoLib’s KMC crypto service integration is vulnerable to a heap buffer overflow when decoding Base64-encoded ciphertext/cleartext fields returned by the KMC service. The decode destination buffer is sized using an expected output length (len_data_out), but the Base64 decoder writes output based on the actual Base64 input length and does not enforce any destination size limit. An oversized Base64 string in the KMC JSON response can cause out-of-bounds writes on the heap, resulting in process crash and potentially code execution under certain conditions. This issue has been patched in version 1.4.3.
CVE-2026-220270.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, the convert_hexstring_to_byte_array() function in the MariaDB SA interface writes decoded bytes into a caller-provided buffer without any capacity check. When importing SA fields from the database (e.g., IV, ARSN, ABM), a malformed or oversized hex string in the database can overflow the destination buffer, corrupting adjacent heap memory. This issue has been patched in version 1.4.3.
CVE-2026-220260.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, the libcurl write_callback function in the KMC crypto service client allows unbounded memory growth by reallocating response buffers without any size limit or overflow check. A malicious KMC server can return arbitrarily large HTTP responses, forcing the client to allocate excessive memory until the process is terminated by the OS. This issue has been patched in version 1.4.3.
CVE-2026-220250.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, when the KMC server returns a non-200 HTTP status code, cryptography_encrypt() and cryptography_decrypt() return immediately without freeing previously allocated buffers. Each failed request leaks approximately 467 bytes. Repeated failures (from a malicious server or network issues) can gradually exhaust memory. This issue has been patched in version 1.4.3.
CVE-2026-220240.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, the cryptography_encrypt() function allocates multiple buffers for HTTP requests and JSON parsing that are never freed on any code path. Each call leaks approximately 400 bytes of memory. Sustained traffic can gradually exhaust available memory. This issue has been patched in version 1.4.3.
CVE-2026-220230.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, there is an out-of-bounds heap read vulnerability in cryptography_aead_encrypt(). This issue has been patched in version 1.4.3.
CVE-2026-219000.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, an out-of-bounds heap read vulnerability in cryptography_encrypt() occurs when parsing JSON metadata from KMC server responses. The flawed strtok iteration pattern uses ptr + strlen(ptr) + 1 which reads one byte past allocated buffer boundaries when processing short or malformed metadata strings. This issue has been patched in version 1.4.3.
CVE-2026-218990.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, in base64urlDecode, padding-stripping dereferences input[inputLen - 1] before checking that inputLen > 0 or that input != NULL. For inputLen == 0, this becomes an OOB read at input[-1], potentially crashing the process. If input == NULL and inputLen == 0, it dereferences NULL - 1. This issue has been patched in version 1.4.3.
CVE-2026-218980.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, the Crypto_AOS_ProcessSecurity function reads memory without valid bounds checking when parsing AOS frame hashes. This issue has been patched in version 1.4.3.
CVE-2026-218970.00—0.00Jan 10, 2026CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, the Crypto_Config_Add_Gvcid_Managed_Parameters function only checks whether gvcid_counter > GVCID_MAN_PARAM_SIZE. As a result, it allows up to the 251st entry, which causes a write past the end of the array, overwriting gvcid_counter located immediately after gvcid_managed_parameters_array[250]. This leads to an out-of-bounds write, and the overwritten gvcid_counter may become an arbitrary value, potentially affecting the parameter lookup/registration logic that relies on it. This issue has been patched in version 1.4.3.
CVE-2025-640960.00—0.00Oct 30, 2025CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to 1.4.2, there is a missing bounds check in Crypto_Key_update() (crypto_key_mgmt.c) which allows a remote attacker to trigger a stack-based buffer overflow by supplying a TLV packet with a spoofed length field. The function calculates the number of keys from an attacker-controlled field (pdu_len), which may exceed the static array size (kblk[98]), leading to an out-of-bounds write and potential memory corruption. This vulnerability is fixed in 1.4.2.
CVE-2025-595340.00—0.00Sep 23, 2025CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.2, there is a command Injection vulnerability in initialize_kerberos_keytab_file_login(). The vulnerability exists because the code directly interpolates user-controlled input into a shell command and executes it via system() without any sanitization or validation. This issue has been patched in version 1.4.2.
CVE-2025-548780.00—0.00Aug 11, 2025CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. A heap buffer overflow vulnerability exists in NASA CryptoLib version 1.4.0 and prior in the IV setup logic for telecommand frames. The problem arises from missing bounds checks when copying the Initialization Vector (IV) into a freshly allocated buffer. An attacker can supply a crafted TC frame that causes the library to write one byte past the end of the heap buffer, leading to heap corruption and undefined behaviour. An attacker supplying a malformed telecommand frame can corrupt heap memory. This leads to undefined behaviour, which could manifest itself as a crash (denial of service) or more severe exploitation. This issue has been patched in version 1.4.0.
CVE-2025-466730.00—0.00Apr 27, 2025NASA CryptoLib before 1.3.2 does not check whether the SA is in an operational state before use, possibly leading to a bypass of the Space Data Link Security protocol (SDLS).
CVE-2025-466740.00—0.00Apr 27, 2025NASA CryptoLib before 1.3.2 uses Extended Procedures that are a Work in Progress (not intended for use during flight), potentially leading to a keystream oracle.
CVE-2025-466750.00—0.00Apr 27, 2025In NASA CryptoLib before 1.3.2, the key state is not checked before use, potentially leading to spacecraft hijacking.
CVE-2025-466720.00—0.00Apr 27, 2025NASA CryptoLib before 1.3.2 does not check the OTAR crypto function returned status, potentially leading to spacecraft hijacking.
