This vulnerability is a stack-based buffer overflow (CWE-121) in NetSupport Manager 14.x versions before 14.12.0000. It can be triggered remotely without authentication, leading to denial of service or limited memory disclosure. The CVSS 4.0 vector indicates it is network exploitable with low attack complexity and no privileges or user interaction required. The vulnerability does not involve confidentiality or integrity impact but has high availability impact. No patch or vendor advisory is provided in the data.

Successful exploitation can cause a denial of service condition on the affected system or leak a limited amount of memory. This could disrupt normal operations of NetSupport Manager and potentially expose some memory contents. There is no evidence of code execution or privilege escalation from the provided information.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor NetSupport Ltd. advisories for updates. Until a fix is available, consider limiting network exposure of NetSupport Manager services to trusted networks only.
