- **CWE:** CWE-78 (OS Command Injection)
- **CVE ID:** CVE-2024-41791 (Example)
- **CVSS Score:** 9.8 (CVSS v3.1 - Critical), 10.0 (CVSS v4.0)
- **CWE:** CWE-798 (Use of Hard-coded Credentials)
- **CVE ID:** CVE-2024-41795 (Example)
- **CVSS Score:** 6.5 (CVSS v3.1 - High), 6.9 (CVSS v4.0)
- **CWE:** CWE-352 (Cross-Site Request Forgery - CSRF)
## Affected Systems
- **Products:** SENTRON 7KT PAC1260 Data Manager
- **Versions:** All versions affected by the listed CVEs. (The device is considered end-of-life for software support.)
- **Configurations:** Vulnerabilities primarily affect the web interface.
## Vulnerability Description
The SENTRON 7KT PAC1260 Data Manager is affected by multiple flaws collectively, including:
1. **OS Command Injection (CVE-2024-41788, -41789, -41790):** Flaws in web interface parameters (input parameters in GET requests, language parameter in POST requests, region parameter in POST requests) allow **authenticated remote attackers** to execute arbitrary code with **root privileges** due to improper input sanitization.
2. **Use of Hard-coded Credentials (CVE-2024-41791, -41792, -41793, -41794):** Found in components related to report creation, these flaws allow attackers to potentially read/clear logs, or gain unauthorized access with hardcoded secrets.
3. **Improper Access Control (CVE-2024-41791):** Unauthenticated remote attacker can read or clear log files due to missing authentication on report creation requests.
4. **CSRF and Password Change Flaws (CVE-2024-41795, -41796):** Unauthenticated attackers can leverage CSRF to trick an administrator into changing arbitrary device settings, including potentially setting a new password without knowing the old one (in combination with CVE-2024-41795).
## Exploitation
- **Status:** Specific exploitation status for all CVEs is **not explicitly detailed** as 'exploited in the wild,' however, several involve authenticated remote code execution (RCE) which are high-value targets. CVE-2024-41791 is exploitable by **unauthenticated** attackers for log access/clearing.
- **Complexity:** Varies. RCE flaws (CVE-2024-41788 to -41790) require authentication (**PR:H**) and are network accessible (**AV:N**). CSRF flaws (CVE-2024-41795, -41796) require user interaction (**UI:R**).
- **Attack Vector:** Primarily **Network** (Remote, requiring various levels of privilege: Authenticated or Unauthenticated).
## Impact
Impact scores reflect the potential for severe compromise across multiple vectors:
- **Confidentiality:** High (Potential for root access and data theft via RCE / log access)
- **Integrity:** High (Ability to execute arbitrary code with root privileges or change critical settings via CSRF)
- **Availability:** High (Ability for an attacker to potentially disrupt service via RCE)
## Remediation
### Patches
- **Software fixes are no longer provided for the SENTRON 7KT PAC1260 Data Manager.**
### Workarounds
1. **Replacement:** Siemens strongly recommends **replacing the device** with the new **SENTRON 7KT PAC1261 Data Manager** and ensuring it is updated to the latest firmware.
2. **Specific Mitigations (CVE-2024-41795, CVE-2024-41796):** Do not access links from untrusted sources while logged in at affected devices.
3. **General Security Recommendations:** Protect network access to devices using appropriate mechanisms and configure the environment according to Siemens' operational guidelines for Industrial Security.
## Detection
The advisory does not explicitly list specific IOCs, but detection should focus on:
- **Web Interface Monitoring:** Look for unusual GET/POST requests targeting input parameters (language, region) or requests for log clearing/creation that lack proper session context.
- **Network Segmentation:** Ensuring the device is inaccessible from untrusted networks is the primary protective measure until replacement occurs.
- **System Logs:** Monitoring for unexpected command execution or privilege escalation attempts on the device.
