| CVE-2021-35587 | Unauthenticated RCE in Oracle Access Manager (OpenSSO Agent) CVE-2021-35587 is a critical (CVSS 9.8) missing-authentication flaw (CWE-306) in the OpenSSO Agent component of Oracle Access Manager, part of Oracle Fusion Middleware. An unauthenticated attacker with network access can send crafted HTTP requests to the affected component and, because the endpoint requires no authentication, achieve takeover of Oracle Access Manager — effectively pre-authentication remote code execution with high impact on confidentiality, integrity, and availability. Organizations running Oracle Access Manager 11.1.2.3.0, 12.2.1.3.0, or 12.2.1.4.0 are affected. The flaw is being actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities Catalog on 2022-11-28, and security press reported more than 150 internet-exposed Oracle Access Management systems. EPSS assigns a 96.3% probability of exploitation within 30 days, although no public proof-of-concept code is known. Do: Apply Oracle's update for CVE-2021-35587 per vendor instructions (delivered via the Oracle Critical Patch Update covering this flaw) to bring Access Manager 11.1.2.3.0, 12.2.1.3.0, and 12.2.1.4.0 to a fixed release; this is the required action in CISA's KEV entry. Until patched, restrict HTTP access to OpenSSO Agent/Access Manager endpoints at the perimeter and review access logs for signs of unauthenticated exploitation. | 9.8 | 96% | KEV |

CISA added a critical flaw impacting Oracle Fusion Middleware, tracked as CVE-2021-35587, to its Known Exploited Vulnerabilities Catalog.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a critical vulnerability impacting Oracle Fusion Middleware, tracked as CVE-2021-35587 (CVSS 3.1 Base Score 9.8), to its Known Exploited Vulnerabilities Catalog.
An unauthenticated attacker with network access via HTTP can exploit the vulnerability to compromise Oracle Access Manager.
“Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Access Manager. Successful attacks of this vulnerability can result in takeover of Oracle Access Manager. CVSS 3.1 Base Score 9.8” states the NIST.
The flaw was reported in March and affects versions 11.1.2.3.0, 12.2.1.3.0 and 12.2.1.4.0. The IT giant fixed the issue in January with the release of the Critical Patch Update.
“This vulnerability was discovered by accident by me and Peterjson while we were analyzing and building PoC for another mega-0day (which is still not fixed by now 😉 ).” reads the post published security researcher Nguyen Jang (Janggggg) who reported the flaw alongside peterjson. “It’s quiet easy to access the entrypoint and exploit the vulnerability, so it’s recommend to apply the patch now! It may give the attacker access to OAM server, to create any user with any privileges, or just get code execution in the victim’s server.”
Below is the video PoC published by Nguyen Jang.
CISA orders federal agencies to fix these vulnerabilities by December 19, 2022.
