Remote code execution via oversized GCL hostname
Published Apr 11, 2024 · Updated Aug 9, 2024
Stack overflow in Experion Server allows remote attackers to execute code by sending a malformed GCL message with an oversized hostname. GCL message handling accepts a hostname larger than the server's stack buffer, causing adjacent stack memory to be overwritten. Network access to the GCL service and a specially malformed message are required; successful exploitation executes code or interrupts the server.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=510.1 <=510.2 HF13
- Affected versionversion=511.1 <=511.5 TCU4 HF3
- Affected versionversion=520.1 <=520.1 TCU4
- Affected versionversion=520.2 <=520.2 TCU4
