libhtp

LibHTP is a security-aware parser for the HTTP protocol. Crafted traffic can cause excessive processing time of HTTP headers, leading to denial of service. This issue is addressed in 0.5.46.

CVE-2024-23837 is a vulnerability classified under CWE-770, which concerns allocation of resources without limits or throttling. The affected component, libhtp, is a security-aware HTTP protocol parser widely used in network security tools developed by the Open Information Security Foundation (OISF), such as Suricata. The vulnerability arises when libhtp processes specially crafted HTTP headers that cause it to consume excessive CPU resources due to unbounded allocation or processing loops. This leads to a denial of service condition by exhausting processing capacity, effectively disrupting the availability of services relying on libhtp for HTTP parsing. The flaw does not impact confidentiality or integrity but severely affects availability. Exploitation requires no privileges or user interaction and can be triggered remotely by sending malicious HTTP traffic. The issue was addressed in libhtp version 0.5.46, which introduced limits or throttling mechanisms to prevent excessive resource consumption during header parsing. No public exploits have been reported yet, but the vulnerability’s characteristics make it a credible DoS vector against network security devices or applications using vulnerable libhtp versions.
