Title: HolaCMS Voting Module Directory Traversal Remote File Corruption Vulnerability
Severity: HIGH
Description:
HolaCMS is a content management system that is implemented in PHP.
HolaCMS is prone to a vulnerability that may allow remote users to corrupt files on the server. This is due an input validation error that allows users to submit voting data to an attacker-specified file. This issue is similar to the vulnerability described in BID 12789 (HolaCMS Voting Module Remote File Corruption Vulnerability). It is reported that HolaCMS 1.4.9-1, which was released to address the issue in BID 12789 is still vulnerable to a variant of that issue.
In particular, the voting module writes user-submitted voting data to a file on the computer hosting the software. However, it is reported that remote users may supply their own destination for voting data through the 'vote_filename' variable. Specifically, the attacker can bypass the fix introduced in HolaCMS 1.4.9-1 by including directory traversal sequences such as '../' in the path to a target file.
It has been demonstrated that the issue may be exploited to compromise HolaCMS. Arbitrary system files may also be corrupted in the context of the Web server process. Though unconfirmed, it may be possible to execute arbitrary code by corrupting scripts on the computer.
HolaCMS 1.4.9-1 and prior versions are affected by this issue.
