Vulnerability in the apr_psprintf function in the Apache Portable Runtime (APR) library for Apache 2.0.37 through 2.0.45 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long strings, as demonstrated using XML objects to mod_dav, and possibly other vectors.

  • →Crash/DoS of Apache process (child process termination) following a PROPFIND with malformed XML is a strong indicator of successful exploitation ↗
  • ·Vulnerability only affects Apache 2.0.37 through 2.0.45; Apache 2.0.46 and later are patched. Verify server version before applying detection rules. ↗
  • ·The mod_dav attack vector requires WebDAV to be enabled on the target server; servers without mod_dav loaded are not exploitable via the demonstrated XML object vector. ↗
