Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

The update rebases to the upstream 1.2.50 release which contains the fix. No known exploits are reported in the wild at this time.

Impact

Successful exploitation of this vulnerability could allow an attacker to cause information disclosure or denial of service in systems running the affected mod_jk module versions. This could impact the confidentiality and availability of services relying on mod_jk to connect Apache HTTP Server with Apache Tomcat. There are no known exploits in the wild at this time.

Summary

The mod_jk module for Apache HTTP Server contained a vulnerability identified as CVE-2024-46544, which could lead to information disclosure and denial of service conditions. This vulnerability is addressed by Red Hat through a bug fix update rebasing mod_jk to the upstream 1.2.50 release. The advisory covers Red Hat Enterprise Linux 9.4 and its extended update support and lifecycle variants for x86_64, s390x, ppc64le, and aarch64 architectures. The update mitigates the security issue by incorporating upstream fixes and is distributed as part of Red Hat's official package updates.
