CVE-2025-22152
Published: 10 January 2025
Summary
CVE-2025-22152 is a critical-severity Path Traversal (CWE-22) vulnerability. Its CVSS base score is 9.4 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 45.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-22152 is a high-severity vulnerability in Atheos, a self-hosted browser-based cloud IDE, affecting versions prior to v600. It arises from improper validation of the $path and $target parameters across multiple components, enabling path traversal (CWE-22), code injection (CWE-94), and unquoted search path or element issues (CWE-434). These flaws exist in various PHP files and allow attackers to read, modify, or execute arbitrary files on the server. The CVSS v3.1 base score is 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H), reflecting critical impacts with changed scope.
A privileged user (PR:H) can exploit this over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation grants the ability to perform arbitrary file reads, modifications, or executions, potentially leading to complete server compromise, including data exfiltration, persistence, or further lateral movement.
The issue is addressed in Atheos v600, which includes fixes for parameter validation. Additional details are available in the GitHub security advisory at https://github.com/Atheos/Atheos/security/advisories/GHSA-rgjm-6p59-537v.
