Summary

CVE-2025-71257 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Bmc Footprints Itsm. Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 6.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 AC-25 (Reference Monitor) and AC-3 (Access Enforcement).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations on restricted REST API endpoints and servlets to prevent authentication bypass due to improper security filters.

AC-25 Reference Monitor good match

prevent

Implements a non-bypassable reference monitor to mediate access to system resources, directly countering the filter enforcement failure in BMC FootPrints ITSM.

SI-2 Flaw Remediation good match

prevent

Requires timely application of vendor hotfixes to remediate the specific authentication bypass vulnerability in affected BMC FootPrints versions.

Deeper analysisAI

CVE-2025-71257 is an authentication bypass vulnerability (CWE-306) in BMC FootPrints ITSM versions 20.20.02 through 20.24.01.001. The issue arises from improper enforcement of security filters on restricted REST API endpoints and servlets, allowing attackers to circumvent authentication mechanisms.

Unauthenticated remote attackers can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation enables bypassing access controls to invoke restricted functionality, resulting in unauthorized access to application data and the ability to modify system resources. The CVSS v3.1 base score is 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).

BMC has released hotfixes to remediate the vulnerability, including versions 20.20.02, 20.20.03.002, 20.21.01.001, 20.21.02.002, 20.22.01, 20.22.01.001, 20.23.01, 20.23.01.002, and 20.24.01. Additional mitigation guidance and details are provided in advisories from BMC release notes, Watchtower Labs, and VulnCheck.
