Soplanning 1.32 and earlier generates static links for sharing ICAL calendars with embedded login information, which allows remote attackers to obtain a calendar owner's password via a brute-force attack on the embedded password hash.

→The ICAL sharing URL exposes an MD5 hash computed as md5($user->login . '¤¤' . $user->password). Monitor GET requests to /export_ical.php containing both 'login' and 'hash' query parameters, which leak the password hash for offline brute-force. ↗
→The embedded hash in the ICAL link is an MD5 value. Detect repeated or automated requests to /export_ical.php with varying 'hash' values as a sign of brute-force enumeration. ↗

·The ICAL sharing link is generated statically and embeds the user's login and password hash permanently. Any user who has ever shared an ICAL calendar link has exposed their hash; rotating the password is required to invalidate old links. ↗
·The hash algorithm used is MD5, which is weak and susceptible to fast offline brute-force or rainbow-table attacks. The hash construction is md5(login + '¤¤' + password), meaning the salt is static and predictable. ↗
