CVE-2026-46748 (GCVE-0-2026-46748)

Vulnerability from cvelistv5 – Published: 2026-06-09 08:46 – Updated: 2026-06-09 16:06

Summary

A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The affected system includes a binary that is configured with the cap_dac_override capability. This capability allows the process to bypass file system permission checks, resulting in unrestricted file system access. This could allow a local attacker to escalate privileges leading to arbitrary file modification and gaining root privileges on the system.
