The is_eow function in format.c in CVSTrac before 2.0.1 does not properly check for the "'" (quote) character, which allows remote authenticated users to execute limited SQL injection attacks and cause a denial of service (database error) via a ' character in certain messages, tickets, or Wiki entries.
Multiple cross-site scripting (XSS) vulnerabilities in (1) main.c and (2) login.c for CVSTrac before 1.1.5 allow remote attackers to inject arbitrary HTML and web script.
