Summary
Docling: Unsafe Archive Extraction and XML Parsing in METS-GBS Backend
Details

Impact

The METS-GBS backend's XML parsing and the input document format detection lacked security controls, enabling: - XML External Entity (XXE) attacks to read local files or cause denial of service - Decompression bombs (zip bombs) to exhaust memory and disk space - Unbounded archive extraction consuming system resources

An attacker could craft malicious METS-GBS archives that, when processed, could read sensitive files, exhaust system resources, or cause application crashes.

Patches

Fixed in version 2.91.0. The fix implements: - Secure XML parsing with resolve_entities=False, load_dtd=False, and no_network=True - Configurable limits: 300 MB total extraction size, 10 MB per file, 1000 member count - Cumulative size tracking across all extractions - Early termination when limits are exceeded - Secure format detection of METS-GBS tar archives with _detect_mets_gbs() method: maximum file size (10 MB per file), maximum member count (1000 members), and exception handling to gracefully fail when limits are exceeded

Workarounds

Avoid processing METS-GBS archives from untrusted sources. If necessary, pre-validate archives in an isolated environment with resource limits.

Vulnerability from github – Published: 2022-07-19 00:00 – Updated: 2022-07-26 00:01
VLAI
Details

Apache CloudStack version 4.5.0 and later has a SAML 2.0 authentication Service Provider plugin which is found to be vulnerable to XML external entity (XXE) injection. This plugin is not enabled by default and the attacker would require that this plugin be enabled to exploit the vulnerability. When the SAML 2.0 plugin is enabled in affected versions of Apache CloudStack could potentially allow the exploitation of XXE vulnerabilities. The SAML 2.0 messages constructed during the authentication flow in Apache CloudStack are XML-based and the XML data is parsed by various standard libraries that are now understood to be vulnerable to XXE injection attacks such as arbitrary file reading, possible denial of service, server-side request forgery (SSRF) on the CloudStack management server.

Vulnerability from github – Published: 2023-09-19 15:30 – Updated: 2024-04-04 07:44
VLAI
Details

Improper Restriction of XML External Entity Reference vulnerability in MIM Assistant and Client DICOM RTst Loading modules allows XML Entity Linking / XML External Entities Blowup.

In order to take advantage of this vulnerability, an attacker must craft a malicious XML document, embed this document into specific 3rd party private RTst metadata tags, transfer the now compromised DICOM object to MIM, and force MIM to archive and load the data.

Users on either version are strongly encouraged to update to an unaffected version (7.2.11+, 7.3.4+).

This issue was found and analyzed by MIM Software's internal security team.  We are unaware of any proof of concept or actual exploit available in the wild.

For more information, visit https://www.mimsoftware.com/cve-2023-3892 https://www.mimsoftware.com/cve-2023-3892

This issue affects MIM Assistant: 7.2.10, 7.3.3; MIM Client: 7.2.10, 7.3.3.

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.
