CVE-2013-0136 in Mutiny Virtual Appliance
Summary
by MITRE
Multiple directory traversal vulnerabilities in the EditDocument servlet in the Frontend in Mutiny before 5.0-1.11 allow remote authenticated users to upload and execute arbitrary programs, read arbitrary files, or cause a denial of service (file deletion or renaming) via (1) the uploadPath parameter in an UPLOAD operation; the paths[] parameter in a (2) DELETE, (3) CUT, or (4) COPY operation; or the newPath parameter in a (5) CUT or (6) COPY operation.

The vulnerability described in CVE-2013-0136 represents a critical directory traversal flaw within the Frontend component of Mutiny software versions prior to 5.0-1.11. This vulnerability exists within the EditDocument servlet and affects remote authenticated users who can exploit multiple pathways to gain unauthorized system access. The flaw stems from insufficient input validation and sanitization of file path parameters, creating opportunities for attackers to manipulate the application's file system operations. The vulnerability impacts core file management functions including upload, delete, cut, and copy operations, making it particularly dangerous for attackers seeking to execute arbitrary code or access sensitive system information. The affected software component operates as a web-based file management interface, providing users with capabilities to interact with server-side file systems through HTTP requests.
The technical implementation of this vulnerability allows attackers to manipulate several specific parameters within the EditDocument servlet to achieve unauthorized file system access. During UPLOAD operations, the uploadPath parameter can be manipulated to specify arbitrary directory locations where files can be uploaded and potentially executed. For DELETE, CUT, and COPY operations, the paths[] parameter enables attackers to target files outside the intended directories, while the newPath parameter in CUT and COPY operations allows for arbitrary file movement. These flaws are classified as directory traversal vulnerabilities under CWE-22, which specifically addresses improper limitation of a pathname to a restricted directory. The vulnerability represents a classic case of insufficient input validation where user-supplied paths are directly incorporated into file system operations without proper sanitization or authorization checks. The lack of proper path validation allows attackers to traverse directory structures and access files that should remain protected, potentially leading to complete system compromise.
The operational impact of this vulnerability extends beyond simple file access to encompass full system compromise capabilities. Attackers can leverage these vulnerabilities to upload malicious files that execute arbitrary code on the target system, effectively gaining remote code execution privileges. The ability to perform file deletion or renaming operations creates additional attack vectors for denial of service conditions and data corruption. Furthermore, the vulnerability enables attackers to read arbitrary files from the system, potentially exposing sensitive configuration files, user credentials, or application source code. This information disclosure capability significantly amplifies the threat level as attackers can gather intelligence about the system architecture and identify additional attack surfaces. The vulnerability affects organizations using Mutiny software in production environments where authenticated users have access to the file management interface, making it particularly dangerous in enterprise settings where file system access controls are critical for maintaining security boundaries.
Organizations should implement immediate mitigations to address this vulnerability through multiple defensive layers. The primary recommendation involves applying the vendor-provided patch or upgrade to Mutiny 5.0-1.11 or later versions where the directory traversal flaws have been resolved. Additionally, implementing proper input validation and sanitization measures within the application code is essential to prevent path manipulation attacks. Network segmentation and access controls should be enforced to limit authenticated user access to only necessary file system locations. The implementation of web application firewalls with rules specifically designed to detect and block directory traversal patterns can provide additional protection layers. Security monitoring should include detection of unusual file operations and access patterns that may indicate exploitation attempts. This vulnerability aligns with several ATT&CK techniques including T1059 for command and script injection, T1074 for data staging, and T1566 for credential access through file system manipulation. Organizations should also conduct thorough security assessments of similar file management interfaces to identify and remediate comparable vulnerabilities. The remediation process should include comprehensive testing to ensure that the patch or code modifications do not introduce regressions in legitimate functionality while effectively addressing the directory traversal attack vectors.
