CVE-2025-63690 Vulnerability Summary

CVE-2025-63690: In pig-mesh Pig versions 3.8.2 and below, when setting up scheduled tasks in the Quartz management function under the system management module, it is possible to execute any Java class with a parameterless constructor and its methods with parameter type String through reflection. At this time, the eval method in Tomcat's built-in class jakarta.el.ELProcessor can be used to execute commands, leading to a remote code execution vulnerability.

Assessing the Risk of CVE-2025-63690

Access Complexity Graph

The exploitability of CVE-2025-63690 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-2025-63690

The exploitability of CVE-2025-63690 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-2025-63690, 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-2025-63690, 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-2025-63690 can result in unauthorized access to sensitive data, severely compromising data privacy.
  • Integrity: High
    CVE-2025-63690 could allow unauthorized modifications to data, potentially affecting system reliability and trust.
  • Availability: High
    CVE-2025-63690 can disrupt system operations, potentially causing complete denial of service (DoS).

CWE Common Weakness Enumeration

CWE-470

CAPEC Common Attack Pattern Enumeration and Classification

  • Reflection Injection CAPEC-138 An adversary supplies a value to the target application which is then used by reflection methods to identify a class, method, or field. For example, in the Java programming language the reflection libraries permit an application to inspect, load, and invoke classes and their components by name. If an adversary can control the input into these methods including the name of the class/method/field or the parameters passed to methods, they can cause the targeted application to invoke incorrect methods, read random fields, or even to load and utilize malicious classes that the adversary created. This can lead to the application revealing sensitive information, returning incorrect results, or even having the adversary take control of the targeted application.
