Published: 27 February 2025
Summary
CVE-2025-1743 is a medium-severity Path Traversal (CWE-22) vulnerability. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 8.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and AC-6 (Least Privilege).
Deeper analysis
CVE-2025-1743 is a path traversal vulnerability (CWE-22) classified as critical in zyx0814 Pichome version 2.1.0. The issue resides in an unknown functionality of the file /index.php?mod=textviewer, where manipulation of the "src" argument enables traversal outside intended directories. It carries a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), reflecting medium severity with low confidentiality impact and no effects on integrity or availability.
Any unauthenticated remote attacker can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows limited disclosure of sensitive files via the path traversal, as indicated by the low confidentiality impact in the CVSS score. The exploit has been publicly disclosed and may be actively used.

Mitigating Controls (NIST 800-53 r5) AI
Validates the 'src' argument in /index.php?mod=textviewer to block path traversal sequences like '../' and ensure only intended files are accessed.
Enforces file access authorizations to deny reads outside the intended directory even if path traversal bypasses input handling.
Applies least privilege to the application process, restricting file system access to prevent disclosure of sensitive files via traversal.
