IBM Sterling Secure Proxy 6.0.3.0, 6.0.2.0, and 3.4.3.2 and IBM Sterling External Authentication Server are vulnerable a buffer overflow, due to the Jetty based GUI in the Secure Zone not properly validating the sizes of the form content and/or HTTP headers submitted. A local attacker positioned inside the Secure Zone could submit a specially crafted HTTP request to disrupt service. IBM X-Force ID: 219133.
AnalysisAI
IBM Sterling Secure Proxy 6.0.3.0, 6.0.2.0, and 3.4.3.2 and IBM Sterling External Authentication Server are vulnerable a buffer overflow, due to the Jetty based GUI in the Secure Zone not properly. Rated medium severity (CVSS 6.5), this vulnerability is no authentication required, low attack complexity. This Buffer Copy without Size Check vulnerability could allow attackers to overflow a buffer to corrupt adjacent memory.
Technical ContextAI
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. IBM Sterling Secure Proxy 6.0.3.0, 6.0.2.0, and 3.4.3.2 and IBM Sterling External Authentication Server are vulnerable a buffer overflow, due to the Jetty based GUI in the Secure Zone not properly validating the sizes of the form content and/or HTTP headers submitted. A local attacker positioned inside the Secure Zone could submit a specially crafted HTTP request to disrupt service. IBM X-Force ID: 219133. Affected products include: Ibm Sterling External Authentication Server, Ibm Sterling Secure Proxy.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.
