Scheduled
Medium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority.
Published severityMedium→Operational priority:Medium, unchanged from published severity.unchanged
Evidence used
No CISA KEV confirmation is currently recorded.
The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
EPSS is 0.94% for the current model date.
Compensating controls
Validate the affected product branch and deploy the verified fixed release.
Restrict the affected network interface to trusted sources where business-safe.
Monitor vendor guidance and exploitation sources for a material change.
Verification
Confirm that the asset runs Apache Software Foundation Apache HTTP Server and falls inside the recorded affected range.
Verify the installed build against the product-specific fixed version after deployment.
Validate exposure, authentication requirements and compensating controls in the actual environment.
Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

Summary
A flaw was found in the mod_proxy_ajp module of httpd. When processing AJP (Apache JServ Protocol) messages, the server fails to properly check if a string is null-terminated before attempting to read it, allowing an attacker or a malformed request to cause a heap-based buffer over-read. This issue potentially leads to memory disclosure and a denial of service.

This issue affects Apache HTTP Server: through 2.4.66.
Users are recommended to upgrade to version 2.4.67, which fixes the issue.
What
Improper Null Termination, Out-of-bounds Read vulnerability in Apache HTTP Server.
This issue affects Apache HTTP Server: through 2.4.66.
Users are recommended to upgrade to version 2.4.67, which fixes the issue.
Why
The product does not terminate or incorrectly terminates a string or array with a null character or equivalent terminator.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No confirmed evidence
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.None recorded
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
Likely attack path
a network path → Improper Null Termination → cause the confidentiality, integrity or availability impact described by the vendor

Weakness ?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-170: Improper Null Termination. The product does not terminate or incorrectly terminates a string or array with a null character or equivalent terminator.
CVSS vector ?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
