CVE-2019-3789 Vulnerability Summary

CVE-2019-3789: Cloud Foundry Routing Release, all versions prior to 0.188.0, contains a vulnerability that can hijack the traffic to route services hosted outside the platform. A user with space developer permissions can create a private domain that shadows the external domain of the route service, and map that route to an app. When the gorouter receives traffic destined for the external route service, this traffic will instead be directed to the internal app using the shadow route.

Assessing the Risk of CVE-2019-3789

Access Complexity Graph

The exploitability of CVE-2019-3789 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-2019-3789

CVE-2019-3789 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-2019-3789, 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-2019-3789, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2019-3789 has no significant impact on data confidentiality.
  • Integrity: High
    CVE-2019-3789 could allow unauthorized modifications to data, potentially affecting system reliability and trust.
  • Availability: None
    CVE-2019-3789 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: 0.054% (probability of exploit)

EPSS Percentile: 24.97% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 75.03% of others.

CWE Common Weakness Enumeration

CWE-269

CAPEC Common Attack Pattern Enumeration and Classification

  • Privilege Abuse CAPEC-122 An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.
  • Privilege Escalation CAPEC-233 An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.
  • Restful Privilege Elevation CAPEC-58 An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
