CVE-2026-35393: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in patrickhener goshs
CVE-2026-35393 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 properly sanitize the POST multipart upload directory, allowing attackers to potentially write files outside the intended directory. This vulnerability has a CVSS score of 9. 8, indicating high impact on confidentiality, integrity, and availability. The issue is fixed in version 2. 0. 0-beta.
AI Analysis
Technical Summary
The vulnerability in goshs (prior to version 2.0.0-beta.3) involves improper limitation of a pathname to a restricted directory (CWE-22). Specifically, the POST multipart upload directory is not sanitized, which can allow an attacker to perform path traversal attacks by crafting malicious file paths. This can lead to unauthorized file writes outside the intended directory, potentially compromising system integrity and availability. The vulnerability is addressed in version 2.0.0-beta.3 where proper sanitization is implemented.
Potential Impact
Successful exploitation of this vulnerability can allow an unauthenticated remote attacker to write files to arbitrary locations on the server filesystem. This can lead to full system compromise, including confidentiality breaches, integrity violations, and denial of service. The CVSS score of 9.8 reflects the critical nature of this vulnerability with network attack vector, no required privileges or user interaction, and high impact on all security properties.
Mitigation Recommendations
A fix is available in goshs version 2.0.0-beta.3, which properly sanitizes the POST multipart upload directory to prevent path traversal. Users should upgrade to version 2.0.0-beta.3 or later to remediate this vulnerability. No other mitigation guidance is provided or necessary once the upgrade is applied.
