CVE-2017-7620 EXPLOIT
6.5
MEDIUM · CVSS 3.0 · EPSS 1.4% (pctl 71)
Patch early
A public exploit exists.
Description
MantisBT before 1.3.11, 2.x before 2.3.3, and 2.4.x before 2.4.1 omits a backslash check in string_api.php and consequently has conflicting interpretations of an initial \/ substring as introducing either a local pathname or a remote hostname, which leads to (1) arbitrary Permalink Injection via CSRF attacks on a permalink_page.php?url= URI and (2) an open redirect via a login_page.php?return= URI.
