CVSS v3.1
Official Description
SquirrelMail 1.4.6 and earlier, with register_globals enabled, allows remote attackers to hijack cookies in src/redirect.php via unknown vectors. NOTE: while "cookie theft" is frequently associated with XSS, the vendor disclosure is too vague to be certain of this.
Technical Analysis
CVE-2006-3665 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
