Exploitation evidence

Disclosed: evidence found.
CVE published 18 Apr 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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.

What to do

Upgrade the Red Hat redhat/gnutls package to 9.3.4.

AI-suggested

A security update is available and should be applied to affected systems. Red Hat has released patched versions of GnuTLS for Red Hat Enterprise Linux 9 and related architectures. Users should follow the official Red Hat advisory (RHSA-2024:1879) for detailed update instructions. Applying these updates will mitigate the vulnerabilities. No additional mitigation actions are indicated by the vendor advisory.

Description

A security update has been released for the GNU Transport Layer Security (GnuTLS) library addressing two vulnerabilities: a side-channel information leak (CVE-2024-28834) known as Minerva, and a potential crash during certificate chain building/verification (CVE-2024-28835). These issues affect various Red Hat Enterprise Linux 9 packages and SUSE distributions. The update is rated as moderate severity by Red Hat and patches are available. No known exploits are reported in the wild.

Impact

The side-channel information leak (CVE-2024-28834) could allow an attacker to gain sensitive information through timing or other side-channel attacks. The crash vulnerability (CVE-2024-28835) could cause denial of service by crashing the GnuTLS library during certificate verification. Both vulnerabilities affect the security and stability of applications relying on GnuTLS for cryptographic operations. No known exploits in the wild have been reported, reducing immediate risk.

Class weaknessLikelihood of exploit: HighOWASP Top 10 A04:2025: Cryptographic Failures (opens in a new tab)
The product uses a broken or risky cryptographic algorithm or protocol.
Architecture and Design · Libraries or Frameworks
When there is a need to store or transmit sensitive data, use strong, up-to-date cryptographic algorithms to encrypt that data. Select a well-vetted algorithm that is currently considered to be strong by experts in the field, and use well-tested implementations.
Architecture and Design
Ensure that the design allows one cryptographic algorithm to be replaced with another in the next generation or version. Where possible, use wrappers to make the interfaces uniform. This will make it easier to upgrade to stronger algorithms.
Architecture and Design
Carefully manage and protect cryptographic keys (see CWE-320). If the keys can be guessed or stolen, then the strength of the cryptography itself is irrelevant.
