Exploitation evidence

Disclosed: evidence found.

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.

AI-suggested

Red Hat has released updated krb5 packages for Red Hat Enterprise Linux 8.8 Extended Update Support that address these vulnerabilities. Users should apply the provided security updates as described in the Red Hat advisory RHSA-2024:4743 and the referenced update instructions (https://access.redhat.com/articles/11258). Since this is an official fix, applying the update fully mitigates the vulnerabilities.

Description

Kerberos is a network authentication system, which can improve the security of your network by eliminating the insecure practice of sending passwords over the network in unencrypted form. It allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos key distribution center (KDC). Security Fix(es): * krb5: GSS message token handling (CVE-2024-37370) * krb5: GSS message token handling (CVE-2024-37371) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

The vulnerabilities affect the GSS message token handling in krb5, potentially impacting the security of the Kerberos authentication process. Since Kerberos is critical for secure network authentication by avoiding unencrypted password transmission, flaws in token handling could undermine authentication integrity or confidentiality. The exact impact details and exploitability are not specified beyond the moderate severity rating by Red Hat. There are no known exploits in the wild at the time of the advisory.

Summary

Red Hat Product Security issued an advisory (RHSA-2024:4743) for krb5 in Red Hat Enterprise Linux 8.8 Extended Update Support to address two vulnerabilities identified as CVE-2024-37370 and CVE-2024-37371. Both vulnerabilities concern GSS message token handling within the Kerberos authentication system, which is used to securely authenticate clients and servers via a trusted third party (the KDC). The advisory rates the security impact as moderate and provides updated krb5 packages to remediate these issues. No CVSS scores are provided in the advisory, but the vendor classifies the impact as moderate.
