Piwigo is an open source photo gallery application for the web. In versions on the 14.x branch, when installing, the secret_key configuration parameter is set to MD5(RAND()) in MySQL. However, RAND() only has 30 bits of randomness, making it feasible to brute-force the secret key. The CSRF token is constructed partially from the secret key, and this can be used to check if the brute force succeeded. Trying all possible values takes approximately one hour. The impact of this is limited. The auto login key uses the user's password on top of the secret key. The pwg token uses the user's session identifier on top of the secret key. It seems that values for get_ephemeral_key can be generated when one knows the secret key. Version 15.0.0 contains a fix for the issue.

Piwigo is an open source photo gallery application. Prior to version 14.0.0beta4, a reflected cross-site scripting (XSS) vulnerability is in the` /admin.php?page=plugins&tab=new&installstatus=ok&plugin_id=[here]` page. This vulnerability can be exploited by an attacker to inject malicious HTML and JS code into the HTML page, which could then be executed by admin users when they visit the URL with the payload. The vulnerability is caused by the insecure injection of the `plugin_id` value from the URL into the HTML page. An attacker can exploit this vulnerability by crafting a malicious URL that contains a specially crafted `plugin_id` value. When a victim who is logged in as an administrator visits this URL, the malicious code will be injected into the HTML page and executed. This vulnerability can be exploited by any attacker who has access to a malicious URL. However, only users who are logged in as administrators are affected. This is because the vulnerability is only present on the `/admin.php?page=plugins&tab=new&installstatus=ok&plugin_id=[here]` page, which is only accessible to administrators. Version 14.0.0.beta4 contains a patch for this issue.
