Product | Affected Versions<\/p>\n

WWBN AVideo | dev master commit 15fed957fb<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability is exploited by sending a specially crafted HTTP request to the image404Raw.php functionality of the affected AVideo product. This allows an attacker to arbitrarily read files, which could reveal sensitive information and potentially lead to system compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a
\nconceptual<\/strong>
\n example of how the vulnerability might be exploited:<\/p>\n

GET \/path\/to\/image404Raw.php?file=..\/..\/..\/..\/..\/etc\/passwd HTTP\/1.1\nHost: vulnerablewebsite.com<\/code><\/pre>\n
In this example, the ‘file’ parameter is manipulated to traverse the file system and read a file that should not be accessible, such as the ‘\/etc\/passwd’ file, which contains user account information.<\/p>\n
Mitigation<\/strong><\/p>\n
Users of the affected product are advised to apply the vendor patch as soon as it becomes available. As a temporary mitigation, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to block or alert on HTTP requests that appear to be exploiting this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
