Oracle Identity Manager REST WebServices Missing Authentication RCE

IdentifiersCVE-2025-61757CWE-306· Missing Authentication for…

CVE-2025-61757 is a critical vulnerability in the REST WebServices component of Oracle Identity Manager, part of Oracle Fusion Middleware. Affected supported versions are 12.2.1.4.0 and 14.1.2.1.0. Oracle describes the issue as an easily exploitable vulnerability that allows an unauthenticated attacker with network access via HTTP to compromise Identity Manager, with successful exploitation resulting in takeover of the product. Supporting reporting further characterizes the flaw as a missing authentication for a critical function in improperly protected REST API endpoints, enabling pre-authenticated remote code execution. Public technical reporting indicates authentication can be bypassed on REST endpoints, including by abusing URL patterns such as appending ";.wadl" and references also mention ?WSDL/.wadl exposure behavior. The vulnerability has CVSS v3.1 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can lead to full takeover of the Oracle Identity Manager instance, with high impact to confidentiality, integrity, and availability. Because Oracle Identity Manager is a core identity governance and provisioning platform, compromise can expose sensitive identity data, allow modification of users, roles, and access policies, enable privilege escalation and lateral movement into connected enterprise systems, and disrupt identity and access management operations. Multiple sources in the provided content describe the issue as enabling pre-authenticated remote code execution and note active exploitation in the wild, including CISA KEV inclusion.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict or remove network exposure to Oracle Identity Manager REST endpoints, especially any public-facing HTTP access. Limit access to trusted administrative networks, block unauthenticated access paths at reverse proxies/WAFs, and monitor for suspicious HTTP POST requests targeting OIM REST WebServices endpoints and URL variants involving WADL/WSDL-style suffixes. Increase logging and detection around authentication bypass attempts, unexpected API access, policy or role changes, and post-exploitation activity. These are compensating controls only and are not substitutes for vendor patching.

Remediation

Patch, then assume compromise.

Apply Oracle's fix released in the October 2025 Critical Patch Update for Oracle Fusion Middleware / Oracle Identity Manager. Upgrade or patch affected supported versions 12.2.1.4.0 and 14.1.2.1.0 to Oracle-provided corrected builds. If running older unsupported releases, migrate to a supported version because unsupported versions may also be affected and Oracle patch coverage is limited to supported releases. After patching, review the environment for signs of prior compromise because patching does not remediate historic attacker access or persistence.
