Description:
Some vulnerabilities have been discovered in Yerba SACphp, which can be exploited by malicious people to disclose sensitive information or bypass certain security restrictions.
1) Input passed to the "mod" parameter in index.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.
2) Input passed to the "mod" parameter within the base64 encoded "SID" parameter is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.
3) A vulnerability is caused due to access restriction being based on the existence of a certain cookie. This can be exploited to gain administrative access to the application by creating the cookie "galleta[sesion]" and assigning it the value "1:1:Username" in base64 encoded form.
These vulnerabilities are confirmed in version 6.3. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly verified and implement proper access restrictions.
