CVE-2011-0794 in Fusion Middleware
Summary
by MITRE
Unspecified vulnerability in the Oracle Outside In Technology component in Oracle Fusion Middleware 8.3.5.0 allows local users to affect availability, related to File ID SDK. NOTE: the previous information was obtained from the April 2011 CPU. Oracle has not commented on claims from a reliable third party that this issue is in (a) sccut.dll or (b) libsc_ut.so in Outside In 8.3.5.x through 8.3.5.5684, as used when using the CAB file identification functionality to parse OneNote (.onepkg) files and other formats.

The vulnerability identified as CVE-2011-0794 resides within Oracle Outside In Technology component of Oracle Fusion Middleware version 8.3.5.0, representing a significant security weakness that can be exploited by local attackers to compromise system availability. This issue specifically relates to the File ID SDK functionality within the Outside In technology stack, which serves as a core component for file identification and processing across various document formats. The vulnerability's classification as unspecified indicates that the exact technical mechanism remains partially obscured, though the impact on system availability is clearly documented. Security researchers have noted that this flaw manifests when processing certain file formats, particularly those involving CAB file identification functionality, which can lead to denial of service conditions that disrupt normal system operations.
The technical exploitation of this vulnerability appears to be centered around the processing of OneNote (.onepkg) files and other document formats through the CAB file identification functionality. According to third-party reports, the issue specifically affects the sccut.dll and libsc_ut.so libraries within the Outside In 8.3.5.x through 8.3.5.5684 versions of the software. These dynamic link libraries serve critical functions in file format recognition and processing, and their improper handling during OneNote file parsing creates conditions that can lead to system instability or complete service disruption. The flaw likely stems from inadequate input validation or memory management when processing malformed or specially crafted OneNote files, potentially causing buffer overflows, null pointer dereferences, or other memory corruption conditions that can crash the application or system services. This vulnerability aligns with CWE-119 which addresses "Improper Access to Memory Location" and represents a classic availability-focused attack vector that can be leveraged to deny legitimate users access to system resources.
From an operational standpoint, this vulnerability presents a substantial risk to organizations utilizing Oracle Fusion Middleware with Outside In Technology, particularly those handling OneNote files or other document formats processed through the affected CAB identification functionality. Local attackers who can execute code on the target system can exploit this weakness to cause service disruptions, application crashes, or complete system downtime, thereby compromising the availability aspect of the CIA triad. The impact extends beyond simple denial of service to potentially affect business continuity and operational efficiency, especially in environments where document processing is critical to daily operations. Organizations may experience cascading effects as dependent systems become unavailable due to the compromised file processing capabilities, creating broader operational disruptions that can extend well beyond the immediate affected component.
Mitigation strategies for CVE-2011-0794 should prioritize immediate patching of affected Oracle Fusion Middleware installations, with particular attention to the specific versions and library components mentioned in the vulnerability report. System administrators should implement network segmentation to limit local access to affected systems and employ monitoring solutions that can detect anomalous file processing behavior indicative of exploitation attempts. The principle of least privilege should be enforced to minimize the potential impact of successful exploitation, ensuring that only necessary users and processes have access to the vulnerable file identification functionality. Organizations should also consider implementing file validation and sanitization processes for OneNote and other potentially affected document formats before processing them through the Outside In Technology stack. Additionally, regular security assessments and vulnerability scanning should be conducted to identify any other potentially affected components within the Oracle Fusion Middleware ecosystem, as this vulnerability may indicate broader issues within the software's file processing architecture that could expose other similar weaknesses. The ATT&CK framework categorizes this vulnerability under privilege escalation and denial of service tactics, highlighting the need for comprehensive security controls that address both local and network-based exploitation vectors.
