Fireshare facilitates self-hosted media and link sharing. Versions 1.2.30 and below allow an authenticated user, or unauthenticated user if the Public Uploads setting is enabled, to craft a malicious filename when uploading a video file. The malicious filename is then concatenated directly into a shell command, which can be used for uploading files to arbitrary directories via path traversal, or executing system commands for Remote Code Execution (RCE). This issue is fixed in version 1.3.0.
AzuraCast is a self-hosted, all-in-one web radio management suite. Versions 0.23.1 mistakenly include an API endpoint that is intended for internal use by the SFTP software sftpgo, exposing it to the public-facing HTTP API for AzuraCast installations. A user with specific internal knowledge of a station's operations can craft a custom HTTP request that would affect the contents of a station's database, without revealing any internal information about the station. In order to carry out an attack, a malicious user would need to know a valid SFTP station username and the coordinating internal filesystem structure. This issue is fixed in version 0.23.2.
Tornado is a Python web framework and asynchronous networking library. Versions 6.5.2 and below use an inefficient algorithm when parsing parameters for HTTP header values, potentially causing a DoS. The _parseparam function in httputil.py is used to parse specific HTTP header values, such as those in multipart/form-data and repeatedly calls string.count() within a nested loop while processing quoted semicolons. If an attacker sends a request with a large number of maliciously crafted parameters in a Content-Disposition header, the server's CPU usage increases quadratically (O(n²)) during parsing. Due to Tornado's single event loop architecture, a single malicious request can cause the entire server to become unresponsive for an extended period. This issue is fixed in version 6.5.3.
Tornado is a Python web framework and asynchronous networking library. In versions 6.5.2 and below, the supplied reason phrase is used unescaped in HTTP headers (where it could be used for header injection) or in HTML in the default error page (where it could be used for XSS) and can be exploited by passing untrusted or malicious data into the reason argument. Used by both RequestHandler.set_status and tornado.web.HTTPError, the argument is designed to allow applications to pass custom "reason" phrases (the "Not Found" in HTTP/1.1 404 Not Found) to the HTTP status line (mainly for non-standard status codes). This issue is fixed in version 6.5.3.
Tornado is a Python web framework and asynchronous networking library. In versions 6.5.2 and below, a single maliciously crafted HTTP request can block the server's event loop for an extended period, caused by the HTTPHeaders.add method. The function accumulates values using string concatenation when the same header name is repeated, causing a Denial of Service (DoS). Due to Python string immutability, each concatenation copies the entire string, resulting in O(n²) time complexity. The severity can vary from high if max_header_size has been increased from its default, to low if it has its default value of 64KB. This issue is fixed in version 6.5.3.
Reflected cross-site scripting vulnerability exists in GroupSession Free edition prior to ver5.7.1, GroupSession byCloud prior to ver5.7.1, and GroupSession ZION prior to ver5.7.1. If a user accesses a crafted page or URL, an arbitrary script may be executed on the web browser of the user.
Stored cross-site scripting vulnerabilities exist in GroupSession Free edition prior to ver5.7.1, GroupSession byCloud prior to ver5.7.1, and GroupSession ZION prior to ver5.7.1. A logged-in user can prepare a malicious page or URL, and an arbitrary script may be executed on the web browser when another user accesses it.
Masa CMS is an open source Enterprise Content Management platform. Versions 7.2.8 and below, 7.3.1 through 7.3.13, 7.4.0-alpha.1 through 7.4.8 and 7.5.0 through 7.5.1 are vulnerable to XSS when an unsanitized value of the ajax URL query parameter is directly included within the <head> section of the HTML page. An attacker can execute arbitrary scripts in the context of the user's session, potentially leading to Session Hijacking, Data Theft, Defacement and Malware Distribution. This issue is fixed in versions 7.5.2, 7.4.9, 7.3.14, and 7.2.9. To work around this issue, configure a Web Application Firewall (WAF) rule (e.g., ModSecurity) to block requests containing common XSS payload characters in the ajax query parameter. Alternatively, implement server-side sanitization using middleware to strip or escape dangerous characters from the ajax parameter before it reaches the vulnerable rendering logic.
In GroupSession Free edition prior to ver5.7.1, GroupSession byCloud prior to ver5.7.1, and GroupSession ZION prior to ver5.7.1, "External page display restriction" is set to "Do not limit" in the initial configuration. With this configuration, the user may be redirected to an arbitrary website when accessing a specially crafted URL.
SQL Injection vulnerability exists in GroupSession Free edition prior to ver5.3.0, GroupSession byCloud prior to ver5.3.3, and GroupSession ZION prior to ver5.3.2. If exploited, information stored in the database may be obtained or altered by an authenticated user.
