Details

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JAXP). Supported versions that are affected are Oracle Java SE: 7u321, 8u311, 11.0.13, 17.01; Oracle GraalVM Enterprise Edition: 20.3.4 and 21.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

Summary
XXE vulnerability in Jenkins Subversion Plugin
Details

Jenkins Subversion Plugin 2.13.1 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control an agent process to have Jenkins parse a crafted changelog file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Jenkins Subversion Plugin 2.13.2 disables external entity resolution for its XML parser.

XXE vulnerability in Jenkins Cobertura Plugin

Cobertura Plugin 1.15 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows a user able to control the input files for the 'Publish Cobertura Coverage Report' post-build step to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Cobertura Plugin 1.16 disables external entity resolution for its XML parser.

GHSA-VQQ8-VPHP-8X9C

Vulnerability from github – Published: 2023-05-24 21:30 – Updated: 2024-04-04 04:20
VLAI
Details

The client in OpenText Archive Center Administration through 21.2 allows XXE attacks. Authenticated users of the OpenText Archive Center Administration client (Versions 16.2.3, 21.2, and older versions) could upload XML files to the application that it did not sufficiently validate. As a result, attackers could craft XML files that, when processed by the application, would cause a negative security impact such as data exfiltration or localized denial of service against the application instance and system of the user running it.

Vulnerability from github – Published: 2022-05-13 01:17 – Updated: 2025-04-12 13:03
VLAI
Details

The Office Open XML (OOXML) feature in Adobe ColdFusion 10 before Update 21 and 11 before Update 10 allows remote attackers to read arbitrary files or send TCP requests to intranet servers via a crafted OOXML spreadsheet containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

    }
  ]
}

Mitigation
Implementation System Configuration

Many XML parsers and validators can be configured to disable external entity expansion.

CAPEC-221: Data Serialization External Entities Blowup

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.
