ARSC Really Simple Chat home.php arsc_language Parameter Path Disclosure
Remote / Network Access Information Disclosure, Input Manipulation
Loss of Confidentiality
Exploit Public Vendor Verified

- 漏洞描述

ARSC Really Simple Chat contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a remote attacker specifies an invalid language file an argument to the home.php script, which will disclose the software's installation path resulting in a loss of confidentiality. While such information is relatively low risk, it is often useful in carrying out additional, more focused attacks.
