The imagecomments function in classes.php in MiniGal b13 allows remote attackers to inject arbitrary PHP code into a file in the thumbs/ directory via the input parameter. NOTE: some of these details are obtained from third party information.

The imagecomments function in classes.php in MiniGal b13 allow remote attackers to inject arbitrary PHP code into a file in the thumbs/ directory via the (1) name or (2) email parameter. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Directory traversal vulnerability in index.php in MiniGal b13 (aka MG2) allows remote attackers to read the source code of .php files, and possibly the content of other files, via a .. (dot dot) in the list parameter.

MiniGal Nano <= 0.3.5 Path Traversal via dir Parameter

MiniGal Nano versions 0.3.5 and prior contain a path traversal vulnerability in index.php via the dir parameter. The application appends user-controlled input to the photos directory and attempts to prevent traversal by removing dot-dot sequences, but this protection can be bypassed using crafted directory patterns. An attacker can exploit this behavior to cause the application to enumerate and display image files from unintended filesystem locations that are readable by the web server, resulting in unintended information disclosure.

MiniGal Nano <= 0.3.5 Reflected XSS via dir Parameter

MiniGal Nano version 0.3.5 and prior contain a reflected cross-site scripting (XSS) vulnerability in index.php via the dir parameter. The application constructs $currentdir from user-controlled input and embeds it into an error message without output encoding, allowing an attacker to supply HTML/JavaScript that is reflected in the response. Successful exploitation can lead to execution of arbitrary script in a victim's browser in the context of the vulnerable application.
