Description

This security bulletin contains information about 2 vulnerabilities.


1) Prototype pollution (CVE-ID: CVE-2019-11358)

CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear


The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The vulnerability exists due to improper input validation. A remote attacker can pass specially crafted input to the application and perform prototype pollution, which can result in information disclosure or data manipulation.


2) XML External Entity injection (CVE-ID: CVE-2019-13990)

CWE-ID: CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to conduct an XML External Entity (XXE) attack on a targeted system.

The vulnerability exists due to insufficient validation of user-supplied XML input in the "initDocumentParser" function in the "xml/XMLSchedulingDataProcessor.java" file. A remote authenticated attacker can submit a malicious job description to the targeted system and conduct an XXE attack.
