Description Tomas Hoger 2008-11-03 09:01:21 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2008-4811 to the following vulnerability:

The _expand_quoted_text function in libs/Smarty_Compiler.class.php in
Smarty 2.6.20 r2797 and earlier allows remote attackers to execute
arbitrary PHP code via vectors related to templates and a \
(backslash) before a dollar-sign character.

Comment 1 Christopher Stone 2008-11-03 16:43:14 UTC

Again, this bug description is confusing an inaccurate.

If I understand this correctly, r2797 *fixes* the problem, and the bug description should say "...in Smarty 2.6.20 r2796 and earlier..."
