CVE-2008-4008: WebLogic Apache Connector stack buffer overflow in BEA Product Suite

Automated analysis

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

critical priorityCVSS 2.0 base score of 10 with network reachability, no authentication, and complete impact, combined with a very high EPSS percentile, warrants urgent attention despite the lack of KEV listing.

What it is

An unspecified vulnerability in the WebLogic Server Plugins for Apache component of BEA Product Suite (versions 10.3, 10.0 MP1, 9.2 MP3, 9.1, 9.0, 8.1 SP6, 7.0 SP7, 6.1 SP7) allows remote attackers to affect confidentiality, integrity, and availability. Oracle's advisory does not describe the flaw, but researchers claim it is a stack-based buffer overflow in the WebLogic Apache Connector triggered by an invalid parameter.

Impact

A remote unauthenticated attacker could fully compromise confidentiality, integrity, and availability of the affected server, potentially leading to code execution or denial of service. The CVSS 2.0 score of 10 reflects complete impact across all three security properties.

Attack surface

Reachable over the network through the Apache HTTP Server plugin that fronts WebLogic Server; the CVSS vector AV:N/AC:L/Au:N indicates no authentication and no user interaction are required. The exact request or parameter that triggers the overflow is not specified in the record.

Exploitation

Not listed in CISA KEV and no public exploit references are tagged, but EPSS is 0.56268 (99th percentile), indicating a high predicted likelihood of exploitation activity.

What to do

• Apply the Oracle October 2008 Critical Patch Update for BEA Product Suite, or upgrade to a supported WebLogic release that includes the fix.
• If patching is not immediately possible, restrict network access to the Apache/WebLogic connector to trusted sources and disable the plugin where it is not required.
• Review and harden the Apache Connector configuration, avoiding exposure of the plugin to untrusted networks.
• Monitor Oracle and vendor advisories for updated guidance, since the original description is incomplete.

Detection

• Inspect Apache and WebLogic connector logs for malformed or unusually long parameters that could indicate buffer overflow attempts.
• Monitor for crashes or restarts of the Apache HTTP Server or WebLogic Server processes that may result from exploitation.
• Use network monitoring to detect anomalous requests to the WebLogic Apache Connector from unexpected sources.
