CVE-2018-0108 (GCVE-0-2018-0108)

Vulnerability from cvelistv5 – Published: 2018-01-18 06:00 – Updated: 2024-12-02 21:35
VLAI
Summary
A vulnerability in Cisco WebEx Meetings Server could allow an unauthenticated, remote attacker to collect customer files via an out-of-band XML External Entity (XXE) injection. An attacker could exploit this vulnerability to gain information to conduct additional reconnaissance attacks. The vulnerability is due to the ability of an attacker to perform an out-of-band XXE injection on the system, which could allow an attacker to capture customer files and redirect them to another destination address. An exploit could allow the attacker to discover sensitive customer data. Cisco Bug IDs: CSCvg36996.

Summary
It was discovered that the XmlUtils class in jbpmmigration 6.5 performed expansion of external parameter entities while parsing XML files. A remote attacker could use this flaw to read files accessible to the user running the application server and, potentially, perform other more advanced XML eXternal Entity (XXE) attacks.

CVE-2017-7465 (GCVE-0-2017-7465)

Vulnerability from cvelistv5 – Published: 2018-06-27 16:00 – Updated: 2024-08-05 16:04
VLAI
Summary
It was found that the JAXP implementation used in JBoss EAP 7.0 for XSLT processing is vulnerable to code injection. An attacker could use this flaw to cause remote code execution if they are able to provide XSLT content for parsing. Doing a transform in JAXP requires the use of a 'javax.xml.transform.TransformerFactory'. If the FEATURE_SECURE_PROCESSING feature is set to 'true', it mitigates this vulnerability.

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.
