CVE-2024-39936
Qt
CVE-2024-39936 is a security vulnerability in the HTTP2 implementation within the Qt framework. This flaw affects Qt versions before 5.15.18, 6.x before 6.2.13, 6.3.x through 6.5.x before 6.5.7, and 6.6.x through 6.7.x before 6.7.3. Specifically, critical code intended to make security decisions about active connections can execute prematurely, before the encrypted() signal is emitted and processed, creating a race condition (CWE-367). The SOCRadar Vulnerability Risk Score (SVRS) for CVE-2024-39936 is 56, indicating a moderate risk. Although not immediately critical (SVRS above 80), the fact that this vulnerability is tagged as "In The Wild" elevates the concern and warrants attention. Exploitation of this vulnerability could lead to compromised connection security, potentially allowing unauthorized access or data interception. Organizations using affected Qt versions should prioritize patching to mitigate the risk.
Description:
CVE-2024-39936 is a vulnerability in Qt's HTTP2 implementation that allows an attacker to make security-relevant decisions about an established connection too early, before the encrypted() signal has been emitted and processed. This could allow an attacker to bypass security measures and gain access to sensitive information.
Key Insights:
- The SVRS of 30 indicates that this vulnerability is not considered critical and does not require immediate action.
- No known threat actors or APT groups are actively exploiting this vulnerability.
- No active exploits have been published for this vulnerability.
- CISA has not issued a warning for this vulnerability.
Mitigation Strategies:
- Update to Qt version 5.15.18, 6.2.13, 6.5.7, or 6.7.3 or later.
- Implement additional security measures, such as using a web application firewall (WAF) or intrusion detection system (IDS).
- Monitor network traffic for suspicious activity.
