Overview<\/strong><\/p>\n

The Common Vulnerabilities and Exposures (CVE) system has identified a critical vulnerability in spimsimulator spim v9.1.24 and earlier versions. This security flaw is given the identifier CVE-2025-29365 and pertains to a buffer overflow vulnerability in the READ_STRING_SYSCALL feature of the software. This vulnerability presents a significant risk to data security and system integrity, as it may lead to system<\/a> compromise or data leakage. If exploited, threat actors can potentially gain unauthorized access<\/a> to sensitive information, alter system operations, or disrupt services.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-29365
\nSeverity: Critical (9.8 CVSS score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a>, potential data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

spimsimulator spim | v9.1.24 and before<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The buffer overflow vulnerability<\/a> in spimsimulator spim v9.1.24 and earlier versions is due to improper bounds checking during the processing of user-supplied input in the READ_STRING_SYSCALL feature. By sending a specially crafted input that exceeds the allocated buffer size, an attacker can overwrite adjacent memory locations, thereby causing the application to crash or execute arbitrary code<\/a>.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how this vulnerability might be exploited:<\/p>\n

$ echo -e 'GET \/vulnerable\/endpoint HTTP\/1.1\\r\\nHost: target.example.com\\r\\nContent-Length: 10000\\r\\n\\r\\n'$(python3 -c 'print(\"A\"*10000)') | nc target.example.com 80<\/code><\/pre>\n
In this example, a hypothetical attacker sends a crafted HTTP GET request<\/a> to a vulnerable endpoint on `target.example.com`. The request includes a `Content-Length` header of `10000`, followed by a string of 10,000 ‘A’ characters generated by a Python script. This string exceeds the buffer size for the READ_STRING_SYSCALL feature, causing a buffer overflow<\/a>.
\nPlease note that this is a conceptual example and may need adjustment to work in a real-world scenario. Exploiting this vulnerability could result in severe consequences, including unauthorized access<\/a>, data leakage, or system compromise. It is strongly recommended that users apply the vendor patch or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
