CVE-2022-28615: Read beyond bounds in ap_strcmp_match()

Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may hypothetically be affected.

Security readout for executives and security teams

This issue affects Apache HTTP Server 2.4.53 and earlier. It can cause a crash or possible information disclosure only if third-party modules or Lua scripts pass an extremely large input buffer to ap_strcmp_match(). Apache states bundled server code cannot be coerced into that call path, which narrows likely real-world exposure. Most exposed systems are Apache HTTP Server 2.4.53 or earlier deployments with custom, third-party, or Lua-based logic using ap_strcmp_match(). Standard installations without such integrations appear less likely to be practically reachable based on Apache's note. Treat this as a high-priority hygiene fix for Apache fleets, especially where custom modules or Lua scripts exist. It is critical by CVSS, but Apache's reachability caveat lowers urgency for plain default deployments. Mitigation focus: Inventory Apache HTTP Server instances running 2.4.53 or earlier.; Review Apache and OS vendor advisories for fixed packages.; Update Apache packages through supported vendor channels..
