CVE-2026-29962: n/a
HSC MailInspector v5.3.3-7 contains a Local File Inclusion (LFI) vulnerability caused by improper control of user-supplied file paths. The endpoint /vendor/phpunit/phpunit.php processes user-controlled parameters that directly affect file access operations without adequate validation, sanitization, or path restriction. This allows a remote attacker to exploit Path Traversal techniques to read arbitrary files from the underlying operating system and application directories, leading to sensitive information disclosure.
AI Analysis
Technical Summary
The vulnerability in HSC MailInspector v5.3.3-7 arises from improper control of user-supplied file paths in the /vendor/phpunit/phpunit.php endpoint. This lack of validation enables remote attackers to exploit path traversal techniques to read arbitrary files from the operating system and application directories, resulting in sensitive information disclosure. The issue is classified under CWE-73 (External Control of File Name or Path). The CVSS 3.1 base score is 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), reflecting a high-severity remote attack vector with no required privileges or user interaction and impact limited to confidentiality.
Potential Impact
Successful exploitation allows remote attackers to read arbitrary files on the affected system, leading to disclosure of sensitive information. There is no impact on integrity or availability reported. The vulnerability can be exploited without authentication or user interaction, increasing the risk of information leakage.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the vulnerable endpoint and consider disabling or removing the /vendor/phpunit/phpunit.php component if not required. Monitor for updates from the vendor regarding patches or mitigations.
