CVE-2024-56322 Vulnerability Summary

CVE-2024-56322: GoCD is a continuous deliver server. GoCD versions 16.7.0 through 24.4.0 (inclusive) can allow GoCD admins to abuse a hidden/unused configuration repository (pipelines as code) feature to allow XML External Entity (XXE) injection on the GoCD Server which will be executed when GoCD periodically scans configuration repositories for pipeline updates, or is triggered by an administrator or config repo admin. In practice the impact of this vulnerability is limited, in most cases without combining with another vulnerability, as only GoCD (super) admins have the ability to abuse this vulnerability. Typically a malicious GoCD admin can cause much larger damage than that they can do with XXE injection. The issue is fixed in GoCD 24.5.0. As a workaround, prevent external access from the GoCD server to arbitrary locations using some kind of environment egress control.

Assessing the Risk of CVE-2024-56322

Access Complexity Graph

The exploitability of CVE-2024-56322 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-2024-56322

No exploitability data is available for CVE-2024-56322.

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-2024-56322, 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-2024-56322, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2024-56322 does not compromise confidentiality.
  • Integrity: None
    CVE-2024-56322 does not impact data integrity.
  • Availability: None
    CVE-2024-56322 does not affect 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: 0.049% (probability of exploit)

EPSS Percentile: 21.27% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 78.73% of others.

CWE-611

CAPEC Common Attack Pattern Enumeration and Classification

  • Data Serialization External Entities Blowup CAPEC-221 This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
