An issue was discovered in Vocera Report Server and Voice Server 5.x through 5.8. There is a Path Traversal for an Unzip operation. The Vocera Report Console contains a websocket function that allows for the restoration of the database from a ZIP archive that expects a SQL import file. During the unzip operation, the code takes file paths from the ZIP archive and writes them to a Vocera temporary directory. Unfortunately, the code does not properly check if the file paths include directory traversal payloads that would escape the intended destination.

An issue was discovered in Vocera Report Server and Voice Server 5.x through 5.8. There is an Access Control Violation for Database Operations. The Vocera Report Console contains a websocket interface that allows for the unauthenticated execution of various tasks and database functions. This includes system tasks, and backing up, loading, and clearing of the database.

An issue was discovered in Vocera Report Server and Voice Server 5.x through 5.8. There is Path Traversal in the Task Exec filename. The Vocera Report Console contains various jobs that are executed on the server at specified intervals, e.g., backup, etc. An authenticated user has the ability to modify these entries and set the executable path and parameters.

An issue was discovered in Vocera Report Server and Voice Server 5.x through 5.8. There is Arbitrary File Upload. The BaseController class, that each of the service controllers derives from, allows for the upload of arbitrary files. If the HTTP request is a multipart/form-data POST request, any parameters with a filename entry will have their content written to a file in the Vocera upload-staging directory with the specified filename in the parameter.

An issue was discovered in Vocera Report Server and Voice Server 5.x through 5.8. There is Path Traversal via the "restore SQL data" filename. The Vocera Report Console contains a websocket function that allows for the restoration of the database from a ZIP archive that expects a SQL import file. The filename provided is not properly sanitized and allows for the inclusion of a path-traversal payload that can be used to escape the intended Vocera restoration directory. An attacker could exploit this vulnerability to point to a crafted ZIP archive that contains SQL commands that could be executed against the database.

Power BI Report Server Spoofing Vulnerability

There's a vulnerability within the Apache Xerces Java (XercesJ) XML parser when handling specially crafted XML document payloads. This causes, the XercesJ XML parser to wait in an infinite loop, which may sometimes consume system resources for prolonged duration. This vulnerability is present within XercesJ version 2.12.1 and the previous versions.

A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included).

Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1.

A Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF) vulnerability exists when Power BI Report Server Template file (pbix) containing HTML files is uploaded to the server and HTML files are accessed directly by the victim. Combining these 2 vulnerabilities together, an attacker is able to upload malicious Power BI templates files to the server using the victim's session and run scripts in the security context of the user and perform privilege escalation in case the victim has admin privileges when the victim access one of the HTML files present in the malicious Power BI template uploaded. The security update addresses the vulnerability by helping to ensure that Power BI Report Server properly sanitize file uploads.
