eggblog contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a remote attacker supplies an invalid 'q' variable in search.php script, which will disclose the software's installation path resulting in a loss of confidentiality. While such information is relatively low risk, it is often useful in carrying out additional, more focused attacks.
Upgrade to version v3.0b or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
