CVE-2023-20008 Vulnerability Summary

CVE-2023-20008: A vulnerability in the CLI of Cisco TelePresence CE and RoomOS Software could allow an authenticated, local attacker to overwrite arbitrary files on the local system of an affected device. This vulnerability is due to improper access controls on files that are in the local file system. An attacker could exploit this vulnerability by placing a symbolic link in a specific location on the local file system of an affected device. A successful exploit could allow the attacker to overwrite arbitrary files on the affected device.

Assessing the Risk of CVE-2023-20008

Access Complexity Graph

The exploitability of CVE-2023-20008 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-2023-20008

The exploitability of CVE-2023-20008 is influenced by multiple factors. Security teams should analyze system configurations and apply appropriate countermeasures to mitigate threats.

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-2023-20008, 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-2023-20008, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2023-20008 has no significant impact on data confidentiality.
  • Integrity: High
    CVE-2023-20008 could allow unauthorized modifications to data, potentially affecting system reliability and trust.
  • Availability: None
    CVE-2023-20008 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: 0.042% (probability of exploit)

EPSS Percentile: 5.02% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 94.98% of others.
