CVE-2024-43663Cri0.649.80.04Jan 9, 2025There are many buffer overflow vulnerabilities present in several CGI binaries of the charging station.This issue affects Iocharger firmware for AC model chargers beforeversion 24120701. Likelihood: High – Given the prevalence of these buffer overflows, and the clear error message of the web server, an attacker is very likely to be able to find these vulnerabilities. Impact: Low – Usually, overflowing one of these buffers just causes a segmentation fault of the CGI binary, which causes the web server to return a 502 Bad Gateway error. However the webserver itself is not affected, and no DoS can be achieved. Abusing these buffer overflows in a meaningful way requires highly technical knowledge, especially since ASLR also seems to be enabled on the charging station. However, a skilled attacker might be able to use one of these buffer overflows to obtain remote code execution. CVSS clarification. The attack can be executed over any network connection the station is listening to and serves the web interface (AV:N), and there are no additional security measure sin place that need to be circumvented (AC:L), the attack does not rely on preconditions (AT:N). The attack does require authentication, but the level of authentication is irrelevant (PR:L), it does not require user interaction (UI:N). The attack has a small impact on the availability of the device (VC:N/VI:N/VA:L). There is no impact on subsequent systems. (SC:N/SI:N/SA:N). While this device is an EV charger handing significant amounts of power, we do not expect  this vulnerability to have a safety impact. The attack can be automated (AU:Y).
CVE-2024-43661Cri0.649.80.00Jan 9, 2025The <redacted>.so library, which is used by <redacted>, is vulnerable to a buffer overflow in the code that handles the deletion of certificates. This buffer overflow can be triggered by providing a long file path to the <redacted> action of the <redacted>.exe CGI binary or to the <redacted>.sh CGI script. This binary or script will write this file path to <redacted>, which is then read by <redacted>.so This issue affects Iocharger firmware for AC models before version 24120701. Likelihood: Moderate – An attacker will have to find this exploit by either obtaining the binaries involved in this vulnerability, or by trial and error. Furthermore, the attacker will need a (low privilege) account to gain access to the <redacted>.exe CGI binary or <redacted>.sh script to trigger the vulnerability, or convince a user with such access send an HTTP request that triggers it. Impact: High – The <redacted> process, which we assume is responsible for OCPP communication, will keep crashing after performing the exploit. This happens because the buffer overflow causes the process to segfault before <redacted> is removed. This means that, even though <redacted> is automatically restarted, it will crash again as soon as it tries to parse the text file. CVSS clarification. The attack can be executed over any network connection the station is listening to and serves the web interface (AV:N), and there are no additional security measure sin place that need to be circumvented (AC:L), the attack does not rely on preconditions (AT:N). The attack does require authentication, but the level of authentication is irrelevant (PR:L), it does not require user interaction (UI:N). The attack leads to reducred availability of the device (VC:N/VI:N/VA:H). THere is not impact on subsequent systems. (SC:N/SI:N/SA:N). Alltough this device is an EV charger handing significant amounts of power, we do not forsee a safety impact. The attack can be automated (AU:Y). Because the DoS condition is written to disk persistantly, it cannot be recovered by the user (R:I).

CVE-2009-20008Hig0.63—0.46Aug 30, 2025Green Dam Youth Escort version 3.17 is vulnerable to a stack-based buffer overflow when processing overly long URLs. The flaw resides in the URL filtering component, which fails to properly validate input length before copying user-supplied data into a fixed-size buffer. A remote attacker can exploit this vulnerability by enticing a user to visit a specially crafted webpage containing a long URL, resulting in arbitrary code execution.
CVE-2010-20119Hig0.63—0.52Aug 21, 2025CommuniCrypt Mail versions up to and including 1.16 contains a stack-based buffer overflow vulnerability in its ANSMTP.dll and AOSMTP.dll ActiveX controls, specifically within the AddAttachments() method. This method fails to properly validate the length of input strings, allowing data to exceed the bounds of a fixed-size stack buffer. When invoked with an overly long string, the control can corrupt adjacent memory structures, including exception handlers, leading to potential control flow disruption.
CVE-2012-10031Hig0.63—0.57Aug 5, 2025BlazeVideo HDTV Player Pro v6.6.0.3 is vulnerable to a stack-based buffer overflow due to improper handling of user-supplied input embedded in .plf playlist files. When parsing a crafted .plf file, the MediaPlayerCtrl.dll component invokes PathFindFileNameA() to extract a filename from a URL-like string. The returned value is then copied to a fixed-size stack buffer using an inline strcpy call without bounds checking. If the input exceeds the buffer size, this leads to a stack overflow and potential arbitrary code execution under the context of the user.
CVE-2011-10008Hig0.63—0.49Jul 31, 2025A stack-based buffer overflow vulnerability exists in MPlayer Lite r33064 due to improper bounds checking when handling M3U playlist files containing long http:// URL entries. An attacker can craft a malicious .m3u file with a specially formatted URL that triggers a stack overflow when processed by the player, particularly via drag-and-drop interaction. This flaw allows for control of the execution flow through SEH overwrite and a DEP bypass using a ROP chain that leverages known gadgets in loaded DLLs. Successful exploitation may result in arbitrary code execution with the privileges of the current user.
