CVE-2019-16766 Vulnerability Summary

CVE-2019-16766: When using wagtail-2fa before 1.3.0, if someone gains access to someone's Wagtail login credentials, they can log into the CMS and bypass the 2FA check by changing the URL. They can then add a new device and gain full access to the CMS. This problem has been patched in version 1.3.0.

Assessing the Risk of CVE-2019-16766

Access Complexity Graph

The exploitability of CVE-2019-16766 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-2019-16766

The exploitability of CVE-2019-16766 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-2019-16766, 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-2019-16766, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: High
    Exploiting CVE-2019-16766 can result in unauthorized access to sensitive data, severely compromising data privacy.
  • Integrity: High
    CVE-2019-16766 could allow unauthorized modifications to data, potentially affecting system reliability and trust.
  • Availability: None
    CVE-2019-16766 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: 0.223% (probability of exploit)

EPSS Percentile: 61.13% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 38.87% of others.
