CWE-611: Improper Restriction of XML External Entity Reference ('XXE')
SAP Sybase Adaptive Server Enterprise (ASE) Version 15.7 ESD 2 contains an XML injection vulnerability, which can lead to information exposure. This is due to the expanded use of XML External Entity (XXE) Processing. The XMLParse procedure is vulnerable to attack. Using a specially crafted SQL request, an authenticated attacker may be able to read files with the permissions of the user running the ASE application.
An authenticated attacker may be able to use the vulnerabilities to read user credentials. This may be used to obtain unauthorized administrative or privileged access to the system.
