CVE-2024-21523 Vulnerability Summary

CVE-2024-21523: All versions of the package images are vulnerable to Denial of Service (DoS) due to providing unexpected input types to several different functions. This makes it possible to reach an assert macro, leading to a process crash. **Note:** By providing some specific integer values (like 0) to the size function, it is possible to obtain a Segmentation fault error, leading to the process crash.

Assessing the Risk of CVE-2024-21523

Access Complexity Graph

The exploitability of CVE-2024-21523 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-2024-21523

With low attack complexity and no required privileges, CVE-2024-21523 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.

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-2024-21523, 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-2024-21523, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2024-21523 has no significant impact on data confidentiality.
  • Integrity: None
    CVE-2024-21523 poses no threat to data integrity.
  • Availability: High
    CVE-2024-21523 can disrupt system operations, potentially causing complete denial of service (DoS).

Exploit Prediction Scoring System (EPSS)

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

EPSS Score: 0.045% (probability of exploit)

EPSS Percentile: 18.35% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 81.65% of others.

CWE Common Weakness Enumeration

CWE-241

CAPEC Common Attack Pattern Enumeration and Classification

  • Passing Local Filenames to Functions That Expect a URL CAPEC-48 This attack relies on client side code to access local files and resources instead of URLs. When the client browser is expecting a URL string, but instead receives a request for a local file, that execution is likely to occur in the browser process space with the browser's authority to local files. The attacker can send the results of this request to the local files out to a site that they control. This attack may be used to steal sensitive authentication data (either local or remote), or to gain system profile information to launch further attacks.
