CVE-2026-60431 in HTTP Server
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: mod_proxy). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle HTTP Server. While the vulnerability is in Oracle HTTP Server, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle HTTP Server accessible data. CVSS 3.1 Base Score 8.6 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N).

This vulnerability resides within the Oracle HTTP Server component known as mod_proxy which operates as a reverse proxy module within the Apache HTTP Server framework. The flaw affects specifically version 12.2.1.4.0 and 14.1.2.0.0 of Oracle Fusion Middleware, representing a critical security weakness that allows unauthenticated remote attackers to compromise the server without requiring any credentials or prior access privileges. The vulnerability's exploitability score of 8.6 on the CVSS 3.1 scale indicates a high severity threat level with significant potential for data compromise.
The technical nature of this flaw involves improper input validation or handling within the mod_proxy module that processes HTTP requests forwarded to backend servers. When the Oracle HTTP Server receives certain malformed or crafted HTTP requests through the proxy functionality, it fails to properly validate the incoming data before processing, potentially allowing attackers to manipulate internal server behavior. This type of vulnerability typically falls under CWE-20, which describes "Improper Input Validation," or potentially CWE-436, "Interpretation Conflict" when dealing with proxy module behaviors. The scope change aspect of this vulnerability means that while the initial attack vector targets Oracle HTTP Server, successful exploitation can potentially impact additional Oracle products that may be integrated within the same infrastructure or share common data repositories.
The operational impact of this vulnerability extends beyond simple data access as attackers could gain complete unauthorized access to all data accessible through the compromised Oracle HTTP Server. This represents a severe confidentiality breach since the CVSS vector indicates a high confidentiality impact with no integrity or availability compromise, suggesting that attackers can read sensitive information without modifying system state or causing denial of service. Organizations running affected versions face significant risk as the vulnerability allows for network-based attacks that do not require authentication, making it particularly dangerous in environments where Oracle HTTP Server serves as a gateway to critical backend systems.
Security professionals should implement immediate mitigations including applying the latest Oracle Critical Patch Updates (CPU) patches that address this specific vulnerability. Network segmentation and firewall rules should be enforced to limit access to the Oracle HTTP Server from trusted networks only, while monitoring should be enhanced to detect anomalous proxy request patterns. The ATT&CK framework categorizes this type of vulnerability under T1190 "Exploit Public-Facing Application" with potential for T1071.004 "Application Layer Protocol: DNS" or T1071.002 "Application Layer Protocol: File Transfer Protocol" techniques if attackers leverage the proxy functionality to redirect traffic. Additionally, implementing Web Application Firewall (WAF) rules that specifically target known exploit patterns for mod_proxy vulnerabilities can provide an additional layer of protection against unauthorized access attempts. Organizations should also conduct thorough vulnerability assessments to identify any other systems that might be indirectly affected due to the scope change implications of this vulnerability.
