CVE-2024-11477
7-zip
CVE-2024-11477 is a critical remote code execution vulnerability in 7-Zip's Zstandard decompression functionality. This integer underflow flaw allows attackers to potentially execute arbitrary code on systems using vulnerable versions of 7-Zip when processing specially crafted files. While the CVSS score is 7.8, the SOCRadar Vulnerability Risk Score (SVRS) is 73, indicating a substantial risk that warrants review, but does not necessitate immediate action based on SOCRadar's scale. The vulnerability stems from inadequate validation of user-supplied data during Zstandard decompression, leading to a buffer overflow. Successful exploitation allows an attacker to execute code within the current process's context. Although not considered "critical" as defined by SOCRadar(SVRS > 80), organizations should prioritize patching to mitigate the risk of malicious actors exploiting this vulnerability. Given that this is listed "In The Wild", this vulnerability is significant because of its potential for widespread impact.
Description
CVE-2024-11477 is a vulnerability with an unknown description at this time. The vulnerability has been assigned an SVRS (SOCRadar Vulnerability Risk Score) of 30, indicating a moderate risk level. While this score is not critical (above 80), it is important to note that the CVE is currently being exploited "In The Wild". This means attackers are actively using this vulnerability, requiring immediate attention and mitigation.
Key Insights
- Limited Information: The lack of a description for CVE-2024-11477 makes it challenging to fully understand the vulnerability's nature, impact, and potential exploitation methods. This lack of information further emphasizes the urgency of immediate investigation and mitigation efforts.
- Active Exploitation: The "In The Wild" tag indicates that malicious actors are actively exploiting this vulnerability. This implies attackers have developed and are using exploits targeting this weakness.
- Unknown Impact: The absence of detailed information on the vulnerability's nature means the potential impact on affected systems is unknown. It is crucial to investigate the vulnerability's scope and impact to determine necessary security measures.
- SVRS as a Guide: While the CVSS score of 0 provides no guidance, the SVRS score of 30, combined with the "In The Wild" status, highlights the importance of proactive security measures. This vulnerability requires attention despite its seemingly moderate SVRS score due to its active exploitation.
Mitigation Strategies
- Urgent Patching: As soon as detailed information regarding the vulnerability becomes available, prioritize patching affected systems. This will mitigate the risk of exploitation and ensure the highest level of security.
- Threat Intelligence: Actively monitor threat intelligence feeds and security advisories for any updates related to CVE-2024-11477. These updates may provide insights into the vulnerability's specifics and potential exploits, enabling more targeted mitigation efforts.
- Network Security: Implement strict network security measures, such as firewalls and intrusion detection systems, to identify and block potential attack attempts.
- Vulnerability Scanning: Conduct regular vulnerability scans to identify systems potentially affected by CVE-2024-11477. This allows for timely identification and remediation of any vulnerable configurations.
