Base vector

AV:N/AC:L/Au:N/C:C/I:N/A:N

Name of the Vulnerable Software and Affected Versions libxml2 versions 2.9.4 and earlier

Description The issue is related to the incorrect restriction of XML links to external objects, making it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document. This allows a remote attacker to access confidential data.

Recommendations For libxml2 versions 2.9.4 and earlier, consider disabling the XML External Entity (XXE) processing until a patch is available. Restrict access to sensitive files and data to minimize the risk of exploitation.
