Details
A weakness has been identified in Kamailio up to 5.8.8/6.0.7/6.1.4/6.2.0-dev1. The impacted element is the function shm_malloc of the file src/modules/cdp/receiver.c of the component CDP Diameter Receiver. Executing a manipulation can lead to heap-based buffer overflow. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 6.0.8 is sufficient to resolve this issue. This patch is called 38711a3e788de0130d48cb485578c482b57d9351/4f62235b6f477b649c5cc18b0c81b4e26c949b98/4f62235b6f477b649c5cc18b0c81b4e26c949b98. You should upgrade the affected component.

"details": "A weakness has been identified in Kamailio up to 5.8.8/6.0.7/6.1.4/6.2.0-dev1. The impacted element is the function shm_malloc of the file src/modules/cdp/receiver.c of the component CDP Diameter Receiver. Executing a manipulation can lead to heap-based buffer overflow. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 6.0.8 is sufficient to resolve this issue. This patch is called 38711a3e788de0130d48cb485578c482b57d9351/4f62235b6f477b649c5cc18b0c81b4e26c949b98/4f62235b6f477b649c5cc18b0c81b4e26c949b98. You should upgrade the affected component.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
