An authorization bypass in b2evolution allows remote, unauthenticated attackers to predict password reset tokens for any user through the use of a bad randomness function. This allows the attacker to get valid sessions for arbitrary users, and optionally reset their password. Tested and confirmed in a default installation of version 7.2.3. Earlier versions are affected, possibly earlier major versions as well.
Multiple SQL injection vulnerabilities in the Starrating plugin before 0.7.7 for b2evolution allow remote attackers to execute arbitrary SQL commands via unspecified vectors.
Multiple PHP remote file inclusion vulnerabilities in b2evolution allow remote attackers to execute arbitrary PHP code via a URL in the (1) inc_path parameter to (a) a_noskin.php, (b) a_stub.php, (c) admin.php, (d) contact.php, (e) default.php, (f) index.php, and (g) multiblogs.php in blogs/; the (2) view_path and (3) control_path parameters to blogs/admin.php; and the (4) skins_path parameter to (h) blogs/contact.php and (i) blogs/multiblogs.php. NOTE: this issue is disputed by CVE, since the inc_path, view_path, control_path, and skins_path variables are all initialized in conf/_advanced.php before they are used
