Description

CVE-2024-43799 is a vulnerability in the Send library, which is used for streaming files from the file system as an HTTP response. The vulnerability allows untrusted user input to be passed to SendStream.redirect(), which can lead to the execution of untrusted code. This vulnerability has a CVSS score of 5, indicating a medium severity level. However, the SOCRadar Vulnerability Risk Score (SVRS) is 38, indicating a higher level of risk. This is because the SVRS takes into account additional factors, such as social media activity, news reports, and associations with threat actors and malware.

Key Insights

• The vulnerability can be exploited by attackers to execute arbitrary code on vulnerable systems.
• The vulnerability is relatively easy to exploit, as it only requires an attacker to send a specially crafted HTTP request to a vulnerable system.
• The vulnerability is actively being exploited by attackers in the wild.
• The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning about the vulnerability, calling for immediate and necessary measures to be taken.

Mitigation Strategies

• Update to the latest version of the Send library (0.19.0 or later).
• Restrict access to the vulnerable code from untrusted sources.
• Implement input validation to prevent untrusted user input from being passed to SendStream.redirect().
• Monitor for suspicious activity and take appropriate action if necessary.
