CVE-2023-2423: A vulnerability was discovered in the Rockwell Automation Armor PowerFlex device when the product sends communications to the local event log. Threat actors could exploit this vulnerability by sending an influx of network commands, causing the product to generate an influx of event log traffic at a high rate. If exploited, the product would stop normal operations and self-reset creating a denial-of-service condition. The error code would need to be cleared prior to resuming normal operations.
The exploitability of CVE-2023-2423 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).
With low attack complexity and no required privileges, CVE-2023-2423 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
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-2023-2423, 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-2023-2423, 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: 0.061% (probability of exploit)
EPSS Percentile: 28.96%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 71.03999999999999% of others.
