Title: LiveJournal CSS HTML Injection Vulnerability
Severity: MODERATE
Description:
LiveJournal is freely available web based personal journal application distributed under the GNU Public License. It is implemented using Perl scripts and requires a MySQL database back end.
LiveJournal is reportedly prone to HTML injection via Cascading Style Sheet (CSS) tags. This issue is due to insufficient sanitization of journal input supplied in CSS styles. This may be exploited by creating a malicious style sheet with embedded script code in the journal entry, which also includes a reference to the style using the HTML CLASS attribute. In this manner, it is possible to inject hostile HTML and script code into journal entries.
This could potentially be exploited to steal cookies from other site users. Other attacks are also possible.
Affected Products:
- LiveJournal LiveJournal 0.0.0
