CVE-2022-1331 – Delta Electronics DMARS Improper Restriction of XML External Entity Reference
https://notcve.org/view.php?id=CVE-2022-1331
In four instances DMARS (All versions prior to v2.1.10.24) does not properly restrict references of XML external entities while processing specific project files, which may allow unauthorized information disclosure. En cuatro casos, DMARS (todas las versiones anteriores a v2.1.10.24) no restringe apropiadamente las referencias de entidades externas XML mientras son procesados archivos de proyecto específicos, lo que puede permitir una divulgación de información no autorizada This vulnerability allows remote attackers to disclose sensitive information on affected installations of Delta Industrial Automation DMARS. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of DMARS files. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose files in the context of the current process. • https://www.cisa.gov/uscert/ics/advisories/icsa-22-104-01 • CWE-611: Improper Restriction of XML External Entity Reference •
