CVE-2003-1192: IA WebMail Server GET request stack buffer overflow

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: medium.

critical priorityRemote unauthenticated code execution with complete impact and a CVSS 2.0 score of 10, plus public exploit references and very high EPSS, make this an urgent exposure for any host still running the product.

What it is

IA WebMail Server 3.1.0 contains a stack-based buffer overflow reachable through a long GET request. A remote, unauthenticated attacker can overflow the buffer and potentially execute arbitrary code on the server. The record gives no fixed version, so it is unclear whether a patched release exists.

Impact

Successful exploitation gives the attacker arbitrary code execution in the context of the webmail server process, which typically means full control of the host. The CVSS 2.0 vector rates confidentiality, integrity and availability impact as complete.

Attack surface

The flaw is reached over the network via HTTP by sending an oversized GET request to the webmail service. No authentication or user interaction is required per the AV:N/AC:L/Au:N vector.

Exploitation

The record is not listed in CISA KEV, but multiple references are tagged Exploit and EPSS is 0.69174 (99.3rd percentile), indicating public exploit material and high predicted exploitation activity. No ransomware association is documented.

What to do

• Apply the vendor fix for IA WebMail Server if one is available; the record does not name a patched version, so confirm with the vendor or replace the product.
• If no patch exists, retire or isolate the webmail server and do not expose it to untrusted networks.
• Place the service behind a reverse proxy or WAF that rejects abnormally long request lines and GET URIs.
• Restrict network access to the webmail service to trusted sources only.
• Monitor the vendor and OSVDB advisories for updated remediation guidance.

Detection

• Inspect web server and proxy logs for GET requests with unusually long request lines or URIs targeting the webmail service.
• Alert on crashes or restarts of the IA WebMail Server process, which may indicate a failed overflow attempt.
• Monitor for unexpected child processes or outbound connections originating from the webmail server host.
• Use network IDS signatures for long-URI HTTP requests against this service.
