CVE-2020-7131: This document describes a security vulnerability in Blade Maintenance Entity, Integrated Maintenance Entity and Maintenance Entity products. All J/H-series NonStop systems have a security vulnerability associated with an open UDP port 17185 on the Maintenance LAN which could result in information disclosure, denial-of-service attacks or local memory corruption against the affected system and a complete control of the system may also be possible. This vulnerability exists only if one gains access to the Maintenance LAN to which Blade Maintenance Entity, Integrated Maintenance Entity or Maintenance Entity product is connected. **Workaround:** Block the UDP port 17185(In the Maintenance LAN Network Switch/Firewall). Fix: Install following SPRs, which are already available: * T1805A01^AAI (Integrated Maintenance Entity) * T4805A01^AAZ (Blade Maintenance Entity). These SPRs are also usable with the following RVUs: * J06.19.00 ? J06.23.01. No fix planned for the following RVUs: J06.04.00 ? J06.18.01. No fix planned for H-Series NonStop systems. No fix planned for the product T2805 (Maintenance Entity).
The exploitability of CVE-2020-7131 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
The exploitability of CVE-2020-7131 is influenced by multiple factors. Security teams should analyze system configurations and apply appropriate countermeasures to mitigate threats.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2020-7131, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2020-7131, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.062% (probability of exploit)
EPSS Percentile: 29.53%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 70.47% of others.
