Overview
CVE-2025-52578 describes an “Incorrect Usage of Seeds in Pseudo-Random Number Generator (CWE-335)” vulnerability found in the High Sec ELM Command Centre Server. This medium-severity vulnerability could allow a sophisticated attacker with physical access to the device to compromise internal device communications.
This issue impacts the following versions of Command Centre Server:
- 9.30 prior to vCR9.30.251028a (distributed in 9.30.2881 (MR3))
- 9.20 prior to vCR9.20.251028a (distributed in 9.20.3265 (MR5))
- 9.10 prior to vCR9.10.251028a (distributed in 9.10.4135 (MR8))
- All versions of 9.00 and prior
Technical Details
The vulnerability stems from the insecure generation of pseudo-random numbers within the High Sec ELM Command Centre Server. The improper use of seeds in the pseudo-random number generator (PRNG) creates a predictable sequence of numbers. An attacker with physical access and sufficient technical expertise could potentially predict these numbers, allowing them to intercept and potentially manipulate internal device communications.
CWE-335 specifically highlights issues arising from predictable random values, which can undermine security mechanisms relying on randomness, such as encryption keys, session identifiers, and other security-sensitive data.
CVSS Analysis
The vulnerability has been assigned a CVSS score of 5.7 (Medium).
- CVSS Vector: [This would ideally contain the CVSS vector string from the NVD, but it’s not available in the provided information. Example: AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N ]
- Explanation: This score reflects the requirement of physical access to exploit the vulnerability. While the impact (compromised internal communications) can be significant, the need for physical proximity reduces the overall severity.
Possible Impact
Successful exploitation of CVE-2025-52578 could lead to the following:
- Compromised Internal Communication: An attacker could intercept and potentially modify communications between different components of the High Sec ELM system.
- Loss of Confidentiality: Sensitive data transmitted within the system could be exposed to the attacker.
- System Manipulation: In some scenarios, the attacker might be able to manipulate the system’s behavior through compromised communication channels.
Mitigation and Patch Steps
To mitigate the risk associated with CVE-2025-52578, it is strongly recommended to upgrade your High Sec ELM Command Centre Server to the following versions or later:
- vCR9.30.251028a (distributed in 9.30.2881 (MR3)) or later for users on the 9.30 branch.
- vCR9.20.251028a (distributed in 9.20.3265 (MR5)) or later for users on the 9.20 branch.
- vCR9.10.251028a (distributed in 9.10.4135 (MR8)) or later for users on the 9.10 branch.
Users running versions 9.00 or earlier should upgrade to one of the supported branches (9.10, 9.20, or 9.30) and then apply the appropriate patch.
