CVE-2026-35392: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in patrickhener goshs
CVE-2026-35392 is a critical path traversal vulnerability in patrickhener's goshs, a SimpleHTTPServer written in Go. Versions prior to 2. 0. 0-beta. 3 do not sanitize file paths during PUT uploads, allowing attackers to potentially write files outside the intended directory. This can lead to full compromise of confidentiality, integrity, and availability of the affected system. The vulnerability is fixed in version 2. 0. 0-beta. 3.
AI Analysis
Technical Summary
The goshs HTTP server before version 2.0.0-beta.3 contains an improper limitation of a pathname to a restricted directory (CWE-22) in the PUT upload functionality implemented in httpserver/updown.go. The lack of path sanitization allows an attacker to perform path traversal attacks, potentially overwriting arbitrary files on the server. This vulnerability has a CVSS 3.0 score of 9.8 (critical) with network attack vector, no privileges required, no user interaction, and impacts confidentiality, integrity, and availability. The issue is resolved in version 2.0.0-beta.3.
Potential Impact
Successful exploitation allows an unauthenticated remote attacker to write files outside the intended directory, leading to complete compromise of the server's confidentiality, integrity, and availability. This could enable arbitrary code execution, data tampering, or denial of service.
Mitigation Recommendations
Upgrade to goshs version 2.0.0-beta.3 or later, where the path traversal vulnerability in the PUT upload handler is fixed by proper path sanitization. Patch status is not explicitly stated but the fix is included in the specified version. No other mitigation is documented.
