CVE-2024-47522: CWE-617: Reachable Assertion in OISF suricata
CVE-2024-47522 is a high-severity vulnerability in Suricata versions prior to 7. 0. 7. It involves a reachable assertion triggered by invalid ALPN values in TLS/QUIC traffic when JA4 matching and logging is enabled, causing Suricata to abort with a panic. This can lead to a denial of service condition. The issue is addressed in Suricata version 7. 0. 7. As a temporary mitigation, disabling JA4 matching can prevent the panic. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
Suricata, a network intrusion detection and prevention engine, contains a reachable assertion vulnerability (CWE-617) in versions before 7.0.7. When JA4 matching and logging is enabled, processing invalid ALPN fields in TLS/QUIC traffic causes the application to abort unexpectedly. This vulnerability results in a denial of service by crashing the Suricata process. The vulnerability is fixed in version 7.0.7. Disabling JA4 matching serves as a workaround until the upgrade is applied.
Potential Impact
The vulnerability causes Suricata to abort with a panic upon encountering invalid ALPN in TLS/QUIC traffic with JA4 enabled, resulting in denial of service. There is no impact on confidentiality or integrity reported. No known active exploitation has been observed.
Mitigation Recommendations
Upgrade Suricata to version 7.0.7 or later, where this vulnerability is fixed. As a temporary workaround, disable JA4 matching and logging to prevent the panic. Monitor vendor advisories for any further updates.
