Description
|
|
Two vulnerabilities have been discovered in the PICA Photo Gallery plugin for WordPress, which can be exploited by malicious people to disclose sensitive information and compromise a vulnerable system.
1) Input passed to the "imgname" parameter in wp-content/plugins/pica-photo-gallery/picadownload.php is not properly verified before being used to download files. This can be exploited to disclose the contents of arbitrary files via directory traversal attacks.
2) An error due to the wp-content/plugins/pica-photo-gallery/picaPhotosResize.php script allowing the upload of files with arbitrary extensions to a folder inside the webroot can be exploited to execute arbitrary PHP code by uploading a malicious PHP script.
The vulnerabilities are confirmed in version 1.0. Other versions may also be affected.
