Title: LPanel Multiple Input Validation Vulnerabilities
Severity: MODERATE
Description:
LPanel is a multi-platform web hosting control panel that allows a user to manage their hosted account through a web-based interface. It is available for Unix and Linux variants.
LPanel is prone to multiple input validation vulnerabilities, all of the vulnerabilities require authentication to be exploited. The following issues are reported:
The domain name value passed to the 'domain' parameter of the 'diagnose.php' script is not sufficiently sanitized. This may allow an authenticated attacker to reset DNS values for target domains that are controlled by LPanel.
Input passed to the 'close', 'pid', and 'open' parameters of the 'view_ticket.php' script is not sufficiently sanitized. An authenticated attacker may leverage this issue to respond to arbitrary support tickets. Additionally, input passed to the 'pid' parameter may be used to launch HTML injection attacks. Other attacks are also possible.
The 'inv' URI parameter, passed to the 'viewreceipt.php' script is not properly sanitized. An authenticated attacker may leverage this issue to view arbitrary receipts. Information disclosed in this manner may be used to aid in further attacks.
The 'editdomain' URI parameter, passed to the 'domains.php' script is not properly sanitized. An authenticated attacker may leverage this issue to change DNS information for arbitrary LPanel accounts.
These issues are reported to exist in LPanel versions 1.59 and prior.
