![]() ![]() ![]() During client installation and repair, a PrinterLogic binary is called by the installer to configure the device. A standard user can create the folder and path file ahead of time and obtain elevated code execution.Īn issue was discovered in Vasion PrinterLogic Client for Windows before 25.0.0.836. During installation, binaries gets executed out of a subfolder in C:\\Windows\\Temp. Windows Hyper-V Remote Code Execution VulnerabilityĪn issue was discovered in Vasion PrinterLogic Client for Windows before 25.0.0.818. This protects all uses of the method against the described vulnerability. In all of the mentioned releases, the maintainers have removed the `LIBXML_NOENT` constant as processing of external entities is out of scope of the parsing logic. Kirby sites that don't use XML parsing in site or plugin code are *not* affected.\n\nThe problem has been patched in Kirby 3.5.8.3, 3.6.6.3, 3.7.5.2, 3.8.4.1, and 3.9.6. uploaded by a user or retrieved from an external URL), attackers may be able to include an external entity in the XML file that will then be processed in the parsing process. If those files are of an external origin (e.g. However they may be used in site or plugin code, e.g. Both the vulnerable method and the data handler are not used in the Kirby core. The `Xml::parse()` method is used in the `Xml` data handler (e.g. ![]() If the name of the external file can be controlled by an attacker, this becomes a vulnerability that can be abused for various system impacts like the disclosure of internal or confidential data that is stored on the server (arbitrary file disclosure) or to perform network requests on behalf of the server (server-side request forgery, SSRF).\n\nKirby's `Xml::parse()` method used PHP's `LIBXML_NOENT` constant, which enabled the processing of XML external entities during the parsing operation. The Kirby core does not use any of the affected methods.\n\nXML External Entities (XXE) is a little used feature in the XML markup language that allows to include data from external files in an XML structure. `Data::decode($string, 'xml')`) or the `Xml::parse()` method in site or plugin code. A vulnerability in versions prior to 3.5.8.3, 3.6.6.3, 3.7.5.2, 3.8.4.1, and 3.9.6 only affects Kirby sites that use the `Xml` data handler (e.g. ![]()
