|---|---|---|---|---|---|---|---|---|
| CVE-2021-3711 | Cri | 0.71 | 9.8 | 0.88 | Aug 24, 2021 | In order to decrypt SM2 encrypted data an application is expected to call the API function EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the "out" parameter can be NULL and, on exit, the "outlen" parameter is populated with… | ||
| CVE-2024-9158 | Hig | 0.55 | 8.4 | 0.00 | Sep 30, 2024 | A stored cross site scripting vulnerability exists in Nessus Network Monitor where an authenticated, privileged local attacker could inject arbitrary code into the NNM UI via the local CLI. | ||
| CVE-2025-24917 | Hig | 0.51 | 7.8 | 0.00 | May 23, 2025 | In Tenable Network Monitor versions prior to 6.5.1 on a Windows host, it was found that a non-administrative user could stage files in a local directory to run arbitrary code with SYSTEM privileges, potentially leading to local privilege escalation. | ||
| CVE-2020-5794 | Hig | 0.51 | 7.8 | 0.00 | Nov 6, 2020 | A vulnerability in Nessus Network Monitor versions 5.11.0, 5.11.1, and 5.12.0 for Windows could allow an authenticated local attacker to execute arbitrary code by copying user-supplied files to a specially constructed path in a specifically named user directory. The attacker… | ||
| CVE-2021-3450 | Hig | 0.50 | 7.4 | 0.18 | Mar 25, 2021 | The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve… | ||
| CVE-2023-5624 | Hig | 0.47 | 7.2 | 0.00 | Oct 26, 2023 | Under certain conditions, Nessus Network Monitor was found to not properly enforce input validation. This could allow an admin user to alter parameters that could potentially allow a blindSQL injection. | ||
| CVE-2025-24916 | Hig | 0.46 | 7.0 | 0.00 | May 23, 2025 | When installing Tenable Network Monitor to a non-default location on a Windows host, Tenable Network Monitor versions prior to 6.5.1 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories… | ||
| CVE-2023-5623 | Hig | 0.46 | 7.0 | 0.00 | Oct 26, 2023 | NNM failed to properly set ACLs on its installation directory, which could allow a low privileged user to run arbitrary code with SYSTEM privileges where NNM is installed to a non-standard location | ||
| CVE-2023-5622 | Hig | 0.46 | 7.1 | 0.00 | Oct 26, 2023 | Under certain conditions, Nessus Network Monitor could allow a low privileged user to escalate privileges to NT AUTHORITY\SYSTEM on Windows hosts by replacing a specially crafted file. | ||
| CVE-2021-23840 | Hig | 0.46 | 7.5 | 0.51 | Feb 16, 2021 | Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will… | ||
| CVE-2021-3712 | Hig | 0.45 | 7.4 | 0.50 | Aug 24, 2021 | ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which is… | ||
| CVE-2021-3449 | Med | 0.43 | 5.9 | 0.63 | Mar 25, 2021 | An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a… | ||
| CVE-2021-23841 | Med | 0.39 | 5.9 | 0.07 | Feb 16, 2021 | The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field… | ||
| CVE-2020-1971 | Med | 0.39 | 5.9 | 0.07 | Dec 8, 2020 | The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This… |
