Description Jan Lieskovsky 2009-05-12 12:49:26 UTC
A, From SquirrelMail vulnerability report

Two issues were fixed that both allowed an attacker to run arbitrary script (XSS) on most any SquirrelMail page by getting the user to click on specially crafted SquirrelMail links.

B, From SquirrelMail vulnerability report:

An issue was fixed wherein input to the contrib/decrypt_headers.php script was not sanitized and allowed arbitrary script execution upon submission of certain values.

Comment 5 Jan Lieskovsky 2009-05-13 12:47:05 UTC
Poc (from svn commit):

+ * Update: strip_tags() won't catch something like
+ * src/right_main.php?sort=0&startMessage=1&mailbox=INBOX&xxx="><script>window.open("http://example.com")</script>
+ * or
+ * contrib/decrypt_headers.php/%22%20onmouseover=%22alert(%27hello%20world%27)%22%3E
+ * because it doesn't bother with broken tags.
+ * htmlspecialchars() is the preferred method.

Comment 7 Jan Lieskovsky 2009-05-14 18:04:52 UTC

Multiple cross-site scripting (XSS) vulnerabilities in SquirrelMail
before 1.4.18 allow remote attackers to inject arbitrary web script or
HTML via vectors involving (1) certain encrypted strings in e-mail
headers, related to contrib/decrypt_headers.php; (2) PHP_SELF; and (3)
the query string (aka QUERY_STRING).
