Michal Kedzior found two vulnerabilities in LDAP Account Manager, a web front-end for LDAP directories.

  • CVE-2018-8763 The found Reflected Cross Site Scripting (XSS) vulnerability might allow an attacker to execute JavaScript code in the browser of the victim or to redirect her to a malicious website if the victim clicks on a specially crafted link.

  • CVE-2018-8764 The application leaks the CSRF token in the URL, which can be use by an attacker to perform a Cross-Site Request Forgery attack, in which a victim logged in LDAP Account Manager might performed unwanted actions in the front-end by clicking on a link crafted by the attacker.
