Exploitation evidence

Disclosed: evidence found.
CVE published 5 Dec 2025
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

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 Red Hat httpd:2.4 to 8.7.

AI-suggested

Red Hat has released updated httpd packages for Red Hat Enterprise Linux 8.6 variants that address these vulnerabilities. Users should apply the security update RHSA-2026:0011 promptly to remediate the issues. Detailed instructions for applying the update are available in the Red Hat advisory and knowledge base article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official update.

Description

Red Hat has issued a security advisory for the Apache HTTP Server (httpd) version 2.4 packages included in Red Hat Enterprise Linux 8.6 variants. The update addresses two vulnerabilities: CVE-2025-55753 involving unintended retry intervals in the mod_md (ACME) module, and CVE-2025-58098 where Server Side Includes improperly add query strings to the #exec cmd directive. These issues have been rated with an Important security impact by Red Hat. The advisory provides updated packages to remediate these vulnerabilities.

Impact

The vulnerabilities affect the mod_md module and Server Side Includes functionality of Apache HTTP Server 2.4 on Red Hat Enterprise Linux 8.6. The mod_md issue involves unintended retry intervals that could affect ACME certificate management processes. The Server Side Includes vulnerability involves improper handling of query strings in the #exec cmd directive, potentially leading to unintended command execution contexts. Red Hat rates the overall security impact as Important, indicating a significant but not critical risk. No known exploits in the wild have been reported at this time.

CWE-190Integer Overflow or Wraparound (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
Requirements
Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.
Requirements
Specify which data in the software should be regarded as sensitive. Consider which types of users should have access to which types of data.
Implementation
Ensure that any possibly sensitive data specified in the requirements is verified with designers to ensure that it is either a calculated risk or mitigated elsewhere.
