CVE-2026-46748 Details
Description
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.
A vulnerability exists in Siemens SINEC INS versions prior to V1.0 SP2 Update 6, where a binary is equipped with the cap_dac_override capability. This capability enables the process to circumvent file system permission checks, leading to unrestricted access to the file system. Consequently, a local attacker could exploit this to escalate privileges, allowing arbitrary file modifications and potentially gaining root access on the system.
Users are advised to update to Siemens SINEC INS version V1.0 SP2 Update 6 or later. For more information, visit the Siemens Industry Support page.
