CVE-2024-7592
Python
CVE-2024-7592 is a denial-of-service vulnerability affecting the CPython 'http.cookies' module. This flaw allows an attacker to craft malicious cookies containing backslashes that, when parsed, consume excessive CPU resources due to quadratic complexity in the parsing algorithm. Although the CVSS score is 7.5, the SOCRadar Vulnerability Risk Score (SVRS) is 68, indicating a potentially elevated risk that is trending toward critical. Attackers exploiting this CWE-400 vulnerability can cause a denial of service by overwhelming the server with cookie parsing requests. This is especially significant because cookie handling is a fundamental part of web application functionality. While rated LOW severity by CPython, the 'In The Wild' tag suggests active exploitation, demanding prompt awareness and mitigation strategies such as input validation and rate limiting. The high SVRS, albeit not critical, warrants careful monitoring and patching when available to prevent potential resource exhaustion.
Description
CVE-2024-7592 is a LOW severity vulnerability in CPython's 'http.cookies' standard library module. It arises when parsing cookies with backslashes in quoted characters, leading to excessive CPU usage due to a quadratic complexity algorithm.
Key Insights
- SVRS Score: 42, indicating a moderate risk.
- Exploit Status: No active exploits have been published.
- CISA Warnings: None issued.
- In the Wild: Not actively exploited by hackers.
Mitigation Strategies
- Update to the latest version of CPython.
- Use a web application firewall (WAF) to block malicious requests.
- Implement input validation to prevent the parsing of malicious cookies.
- Monitor network traffic for suspicious activity.
