CVE-2020-3197: A vulnerability in the API subsystem of Cisco Meetings App could allow an unauthenticated, remote attacker to retain and reuse the Traversal Using Relay NAT (TURN) server credentials that are configured in an affected system. The vulnerability is due to insufficient protection mechanisms for the TURN server credentials. An attacker could exploit this vulnerability by intercepting the legitimate traffic that is generated by an affected system. An exploit could allow the attacker to obtain the TURN server credentials, which the attacker could use to place audio/video calls and forward packets through the configured TURN server. The attacker would not be able to take control of the TURN server unless the same credentials were used in multiple systems.
The exploitability of CVE-2020-3197 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-2020-3197 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-2020-3197, 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-2020-3197, 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: 0.134% (probability of exploit)
EPSS Percentile: 50.12%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 49.88% of others.
