CWE-611

A vulnerability in the web-based interface of Cisco Unified Communications Manager and Cisco Unified Communications Manager Session Management Edition (SME) could allow an unauthenticated, remote attacker to access sensitive information or cause a denial of service (DoS) condition. The vulnerability is due to improper restrictions on XML entities. An attacker could exploit this vulnerability by sending malicious requests to an affected system that contain references in XML entities. A successful exploit could allow the attacker to retrieve files from the local system, resulting in the disclosure of sensitive information, or cause the application to consume available resources, resulting in a DoS condition.

In Apache POI up to 4.1.0, when using the tool XSSFExportToXml to convert user-provided Microsoft Excel documents, a specially crafted document can allow an attacker to read files from the local filesystem or from internal network resources via XML External Entity (XXE) Processing.

PHPOffice PhpSpreadsheet before 1.8.0 has an XXE issue. The XmlScanner decodes the sheet1.xml from an .xlsx to utf-8 if something else than UTF-8 is declared in the header. This was a security measurement to prevent CVE-2018-19277 but the fix is not sufficient. By double-encoding the the xml payload to utf-7 it is possible to bypass the check for the string ‚<!ENTITY‘ and thus allowing for an xml external entity processing (XXE) attack.

XXE in the XML parser library in RealObjects PDFreactor before 10.1.10722 allows attackers to supply malicious XML content in externally referenced resources, leading to disclosure of local file contents and/or denial of service conditions.

A denial of service vulnerability exists when the XmlLite runtime (XmlLite.dll) improperly parses XML input, aka ‘XmlLite Runtime Denial of Service Vulnerability’.

The Custom Report import function in Zoho ManageEngine Firewall Analyzer before 12.3 Build 123224 is vulnerable to XML External Entity (XXE) Injection.
