CVE-2020-26086 Vulnerability Summary

CVE-2020-26086: A vulnerability in the video endpoint API (xAPI) of Cisco TelePresence Collaboration Endpoint (CE) Software could allow an authenticated, remote attacker to gain access to sensitive information on an affected device. The vulnerability is due to improper storage of sensitive information on an affected device. An attacker could exploit this vulnerability by accessing information that should not be accessible to users with low privileges. A successful exploit could allow the attacker to gain access to sensitive information.

Assessing the Risk of CVE-2020-26086

Access Complexity Graph

The exploitability of CVE-2020-26086 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).

Exploitability Analysis for CVE-2020-26086

CVE-2020-26086 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.

Understanding AC and PR

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.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2020-26086, 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.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2020-26086, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: Low
    CVE-2020-26086 could lead to minor leaks of non-critical information without major privacy breaches.
  • Integrity: None
    CVE-2020-26086 poses no threat to data integrity.
  • Availability: None
    CVE-2020-26086 does not impact system availability.

Exploit Prediction Scoring System (EPSS)

The EPSS score estimates the probability that this vulnerability will be exploited in the near future.

EPSS Score: 0.073% (probability of exploit)

EPSS Percentile: 35.06% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 64.94% of others.
