Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly addresses the CVE by requiring timely remediation of the POST request handling flaw through vendor patches to versions 10.1.2 or 9.2.13.

prevent

Mitigates the vulnerability by enforcing secure configuration settings, such as disabling request buffering via proxy.config.http.request_buffer_enabled=0 as the vendor workaround.

prevent

Provides protection against the unauthenticated remote DoS attack causing application crashes by limiting effects of resource exhaustion from malformed POST requests.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Remote unauthenticated exploitation of public-facing Apache Traffic Server causes application crash/infinite loop resulting in DoS; directly matches Exploit Public-Facing Application and Application or System Exploitation for endpoint DoS.

issue. A workaround for older versions is to set proxy.config.http.request_buffer_enabled to 0 (the default value is 0).

Deeper analysisAI

CVE-2025-58136 is a vulnerability in Apache Traffic Server stemming from a bug in POST request handling that causes a crash under certain conditions. It affects versions 10.0.0 through 10.1.1 and 9.0.0 through 9.2.12.

An unauthenticated remote attacker with network access can exploit this issue with low complexity and no user interaction required, resulting in a denial-of-service condition via application crash. The CVSS v3.1 base score is 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), with the impact limited to high availability disruption and associated with CWE-670 (Always-Infinite Loop).

The Apache advisory, detailed in the mailing list announcement at https://lists.apache.org/thread/2s11roxlv1j8ph6q52rqo1klvl01n14q, recommends upgrading to fixed versions 10.1.2 or 9.2.13. A workaround for unpatched versions is to set proxy.config.http.request_buffer_enabled to 0, which is the default value.
