KNet web server contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code. Updates are not available.
A vulnerability in KNet web server version 1.04b for Windows could allow an unauthenticated, remote attacker to execute arbitrary code.
The vulnerability is due to insufficient bounds checks on user-supplied input by the affected software. An attacker could exploit the vulnerability by transmitting crafted HTTP packets to a targeted system. If successful, the attacker could cause a stack-based buffer overflow error that could corrupt memory. The attacker could use the memory corruption to execute arbitrary code with elevated privileges. A successful exploit could allow the attacker to cause a complete system compromise.
Proof-of-concept code that exploits this vulnerability is publicly available.
Administrators may consider using IP-based access control lists (ACLs)
to allow only trusted systems to access the affected systems.
Administrators are advised to implement an intrusion
prevention system (IPS) or intrusion detection system (IDS) to help
detect and prevent attacks that attempt to exploit this vulnerability.
The vendor has not confirmed the vulnerability and software updates are not available.
The security vulnerability applies to the following combinations of products.
