Title: OmniHTTPD Long Request Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
OmniHTTPD is a webserver for Microsoft Windows operating systems.
OmniHTTPD is prone to a remotely exploitable buffer overflow condition. This problem is in the handling of requests containing overly long headers. In particular, this issue may be exploited if an overly long HTTP Version header is sent to the webserver. The type of request does not matter (GET, POST, etc.). This condition is known to occur when 4096+ bytes are sent in the header field.
Exploitation of this issue may cause a denial of service condition or result in execution of arbitrary attacker-supplied instructions with the privileges of the webserver process.
OmniHTTPD normally runs with SYSTEM privileges. If this issue is successfully exploited by an attacker to execute arbitrary code, this may result in a full compromise of the underlying host.
This issue was reported in version 2.09 of the software. Other versions may also be affected.
Affected Products:
- Omnicron OmniHTTPD 2.0.09
