WORKAROUNDS AND MITIGATIONS

Siemens has identified the following specific workarounds and mitigations that customers can apply to reduce the risk:

CVE-2025-40760

For clusters not using the UGERest API/daemon remove the setuid-root bit from the binaries for all architectures: chmod u-s $SGE_ROOT/utilbin/<arch>/authuser.

CVE-2025-40763

For non Windows clusters remove the setuid-root bit from the "sgepasswd" binary for all installed architectures: chmod u-s $SGE_ROOT/bin/<arch>/sgepasswd.

Product-specific remediations or mitigations can be found in the section Known Affected Products.
Please follow the General Security Recommendations.

GENERAL SECURITY RECOMMENDATIONS

As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals.

VULNERABILITY DESCRIPTION

Un-/Collapse All

This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.

Vulnerability CVE-2025-40760

Affected products do not properly handle error messages and discloses sensitive password hash information when processing user authentication requests. This could allow a local attacker to extract password hashes for privileged accounts, which can then be subjected to offline brute-force attacks.

CVSS v3.1 Base Score	5.5
CVSS v3.1 Vector	CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
CVSS v4.0 Base Score	6.8
CVSS v4.0 Vector	CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
CWE	CWE-209: Generation of Error Message Containing Sensitive Information

Vulnerability CVE-2025-40763

Affected products do not properly validate environment variables when loading shared libraries, allowing path hijacking through malicious library substitution. This could allow a local attacker to execute arbitrary code with superuser privileges by manipulating the environment variable and placing a malicious library in the controlled path.

CVSS v3.1 Base Score	7.8
CVSS v3.1 Vector	CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
