Full Report
Location Intelligence before V4.4 is affected by multiple vulnerabilities that could allow an attacker in an on-path position to read and modify data passed over the connection between legitimate clients and the affected product or brute force user passwords. Siemens has released a new version for Location Intelligence family and recommends to update to the latest version. The update is available from Siemens Online Software Delivery (OSD).
Analysis Summary
When analyzing the provided advisory, it is important to note that the cumulative impact of multiple vulnerabilities is present, but the vendor advisory groups the fix without assigning a single consolidated high-profile identifier, listing three distinct CVEs. For this summary, the highest resulting risk score (CVSS 4.0) from the listed CVEs will be used for general context while detailing each CVE uniquely.
# Vulnerability: Multiple Vulnerabilities in Siemens Location Intelligence (Data Interception and Password Brute Force)
## CVE Details
- CVE ID: CVE-2024-41681, CVE-2024-41682, CVE-2024-41683
- CVSS Score:
- CVE-2024-41681: 6.0 (CVSS v4.0) (Medium/High)
- CVE-2024-41682: 6.9 (CVSS v4.0) (Medium/High)
- CVE-2024-41683: 6.9 (CVSS v4.0) (Medium/High)
- CWE: CWE-326 (Inadequate Encryption Strength), CWE-307 (Improper Restriction of Excessive Authentication Attempts), CWE-521 (Weak Password Requirements)
## Affected Systems
- Products: Location Intelligence family
- Versions: All versions prior to V4.4
- Configurations: No specific configuration details provided beyond being insecure defaults present in prior versions.
## Vulnerability Description
The advisory describes three distinct vulnerabilities impacting Location Intelligence prior to V4.4:
1. **CVE-2024-41681 (Weak Ciphers):** The web server supports weak ciphers by default. An unauthenticated attacker in an on-path position can read and modify data passed over the connection between legitimate clients and the affected device.
2. **CVE-2024-41682 (Excessive Authentication Attempts):** The product does not properly restrict excessive authentication attempts, allowing an unauthenticated remote attacker to conduct brute force attacks against user passwords.
3. **CVE-2024-41683 (Weak Password Policy):** The product fails to enforce a strong user password policy, which facilitates brute force attacks against user passwords.
## Exploitation
- Status: Exploitation status is not explicitly stated ("E:P" in the CVSS vector typically refers to Proof of Concept existence or known exploitability at the time of scoring, but the summary does not state "Exploited in the wild"). Assume PoC may exist for the password brute-forcing vectors.
- Complexity:
- CVE-2024-41681: High (AC:H) due to required on-path position.
- CVE-2024-41682/41683: Low (AC:L) as these are network-based authentication flaws.
- Attack Vector:
- CVE-2024-41681: Adjacent Network (AV:A)
- CVE-2024-41682/41683: Network (AV:N)
## Impact
| Vulnerability | Confidentiality | Integrity | Availability |
| :--- | :--- | :--- | :--- |
| CVE-2024-41681 | Low (L) | High (H) | High (H) |
| CVE-2024-41682 | Low (L) | None (N) | None (N) |
| CVE-2024-41683 | Low (L) | None (N) | None (N) |
*Note: The reported impact for CVE-2024-41681 is $C:L/I:H/A:H$. For the password attacks (41682/41683), the direct impact is listed as $C:L/I:N/A:N$ (potential account compromise leading to future impact).*
## Remediation
### Patches
- Update Location Intelligence family to **V4.4 or later version**. Updates are available from Siemens Online Software Delivery (OSD).
### Workarounds
- Product-specific remediations or mitigations are available by following the guidance in the "Affected Products and Solution" section of the advisory (not detailed here).
- Follow general security recommendations, including protecting network access and configuring the environment according to Siemens' operational guidelines for Industrial Security.
## Detection
- **Indicators of Compromise:** Unauthorized modification of data transmitted over connections, or successful login attempts via brute-forced credentials.
- **Detection methods and tools:** Monitoring network traffic for evidence of weak cipher negotiation (e.g., TLS downgrades) and extensive failed/successful login attempts against user accounts.
