Confidentiality: High
Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 11 Nov 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Restrict local access to systems running Siemens Altair Grid Engine to trusted and authorized personnel only, minimizing the risk of local exploitation.
Implement strict access controls and monitoring on user accounts with privileges on the grid engine to detect any suspicious activity.
Employ multi-factor authentication (MFA) for privileged accounts where possible to reduce the risk of credential compromise.
Monitor system logs for unusual authentication error messages or attempts that may indicate exploitation attempts.
Once Siemens releases a patch or update for version V2026.0.0 or later, prioritize timely deployment of the update to remediate the vulnerability.
Consider using host-based intrusion detection systems (HIDS) to alert on abnormal local access or error message patterns.
Educate system administrators and users about the risks of local privilege escalation and the importance of safeguarding credentials.
If feasible, isolate critical grid engine systems within segmented network zones to limit lateral movement in case of compromise.

Description

A vulnerability has been identified in Altair Grid Engine (All versions < V2026.0.0). 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.

Impact

For European organizations, the exposure of password hashes for privileged accounts can lead to significant security risks. If an attacker successfully brute-forces these hashes, they could gain elevated access to critical grid engine resources, potentially compromising sensitive computational tasks, data, and infrastructure. This could result in unauthorized data access, disruption of scientific or industrial computing workflows, and lateral movement within the network. The impact is particularly concerning for sectors relying on Siemens Altair Grid Engine for critical operations, such as research institutions, manufacturing, energy, and telecommunications. Confidentiality breaches could lead to intellectual property theft or exposure of sensitive operational data. Although the vulnerability requires local access, insider threats or compromised user accounts could be leveraged to exploit it. Given the medium severity, the risk is moderate but should not be underestimated, especially in environments with high-value targets and stringent compliance requirements under GDPR and other European data protection laws.

CWE-209Generation of Error Message Containing Sensitive Information (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A10:2025: Mishandling of Exceptional Conditions (opens in a new tab)
The product generates an error message that includes sensitive information about its environment, users, or associated data.
Implementation
Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended).
Implementation
Handle exceptions internally and do not display errors containing potentially sensitive information to a user.
Implementation · Attack Surface Reduction
Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
