- CVSS Score: **8.2** (CVSS v3.1) / **8.7** (CVSS v4.0)
- CWE: Not explicitly listed for all, but CVE-2024-38879 mentions **CWE-20: Improper Input Validation** (Path Traversal).
## Affected Systems
- Products: Omnivise T3000 (General), Omnivise T3000 R9.2, Omnivise T3000 Application Server R9.2, Omnivise T3000 Domain Controller R9.2, Omnivise T3000 Network Intrusion Detection System (NIDS) R9.2, Omnivise T3000 Product Data Management (PDM) R9.2, Omnivise T3000 Security Server R9.2, Omnivise T3000 Terminal Server R9.2, Omnivise T3000 Thin Client R9.2. (Also includes R8.2 SP3 and SP4 mentioned in update V1.1).
- Versions: All listed versions of the affected Omnivise T3000 components are vulnerable, specific versions are not detailed beyond the R9.2 designation and specific R8.2 maintenance releases.
- Configurations: Specific configuration details vary by CVE, but the vulnerability related to CVE-2024-38879 involves an internal application port being exposed on the public network interface.
## Vulnerability Description
Omnivise T3000 contains multiple vulnerabilities that could allow an attacker to escalate privileges. Specific technical details mentioned:
* **CVE-2024-38879 (CVSS v3.1: 7.5):** Path Traversal vulnerability due to improper input validation, allowing an attacker to imitate a path to a restricted directory. Additionally, the affected system exposes an internal application port on the public network interface, enabling circumvention of authentication to directly access the exposed application.
## Exploitation
- Status: **PoC available** (Implied due to CVSS E:P - Exploitability Maturity of Proof-of-Concept)
- Complexity: **Low (AC:L)** for the documented vulnerabilities.
- Attack Vector: Varies, but CVE-2024-38879 specifically indicates **Network (AV:N)** attack vector.
## Impact
The general impact across the vulnerabilities is **Privilege Escalation**. Specific impact for CVE-2024-38879 (CVSS v3.1):
- Confidentiality: **High (C:H)**
- Integrity: Low (I:N - Not explicitly indicated for this CVE, generally assumed low if only C high)
- Availability: Low (A:N)
## Remediation
### Patches
Siemens Energy has released patches for several affected products. Users must coordinate the installation of the following where applicable:
* **System Software Patch 22.173.20**
* **System Software Patch 22.173.52**
* **Application Software Patch 09.0.19.06** (For Omnivise T3000 Application Server R9.2)
* Siemens Energy is preparing further fixes for versions still under maintenance.
### Workarounds
* Apply additional mitigations detailed in **Omnivise T3000 Technical News 2024-089**.
* For products where fixes are not yet available, apply countermeasures recommended in the advisory.
* *Specific Note for Security Server R9.2:* System Software Patch 22.173.20 is not required for the Security Server itself but must be deployed to systems affected by CVE-2024-38876.
## Detection
- Detection methods involve cross-referencing affected system activity logs against known indicators related to path traversal attempts or unauthorized access to internal ports, as detailed within the specific Technical News (2024-089). Precise Indicators of Compromise (IOCs) are found in the vendor documentation.
