FreeBSD : FreeBSD -- TCP: remotely exploitable DoS vector (mbuf leak) (7aa913e9-28d1-11f1-b35e-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 7aa913e9-28d1-11f1-b35e-bc241121aa0a advisory. When a challenge ACK is to be sent tcprespond constructs and sends the challenge ACK and consumes the...

Use of Less Trusted Source

Overview wwbn/avideo is an Audio and Video Platform or simply "A Video Platform". Affected versions of this package are vulnerable to Use of Less Trusted Source via the getRealIpAddr function. An attacker can bypass IP-based access controls, rate limiting, or forge audit log entries by sending...

AVideo vulnerable to IP Address Spoofing via Untrusted HTTP Headers in getRealIpAddr()

Summary The getRealIpAddr function in objects/functions.php trusts user-controlled HTTP headers to determine the client's IP address. An attacker can spoof their IP address by sending forged headers, bypassing any IP-based access controls or audit logging. Vulnerable Code File:...

Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS due to the lack of rate limiting in the login process. An attacker can exhaust server resources by sending a large number of parallel login requests via a single HTTP/2 packet, potentially causing the server to cra...
