The GOsa_Filter_Settings cookie in GONICUS GOsa 2.7.5.2 is vulnerable to PHP objection injection, which allows a remote authenticated attacker to perform file deletions (in the context of the user account that runs the web server) via a crafted cookie value, because unserialize is used to restore filter settings from a cookie.
2) Improper access control (CVE-ID: CVE-2019-11187)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
Incorrect Access Control in the LDAP class of GONICUS GOsa through 2019-04-11 allows an attacker to log into any account with a username containing the case-insensitive substring "success" when an arbitrary password is provided.
3) Cross-site scripting (CVE-ID: CVE-2018-1000528)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
