Vulnerability from github – Published: 2026-05-29 00:38 – Updated: 2026-05-29 00:38

Details

Lakeside SysTrack Agent versions prior to 11.2.1.28, 11.3.0.38, 11.4.0.24, 11.5.0.15 contain an out-of-bounds read vulnerability in the Command ID 30 UDP packet handler that allows remote attackers to crash the application by sending a specially crafted UDP packet. Attackers can send a malformed packet with an invalid memory address at offset 0x4 in the payload to trigger an access violation and cause a denial of service.

Severity

7.5 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

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.
