There is a remote stack-based buffer overflow (SEH) in register.ghp in EFS Software Easy Chat Server versions 2.0 to 3.1. By sending an overly long username string to registresult.htm for registering the user, an attacker may be able to execute arbitrary code.

EChat Server 3.1 contains a buffer overflow vulnerability in the chat.ghp endpoint that allows remote attackers to execute arbitrary code by supplying an oversized username parameter. Attackers can send a GET request to chat.ghp with a malicious username value containing…

Stack-based buffer overflow vulnerability in Easy Chat Server 3.1 version. An attacker could send an excessively long username string to the register.ghp file asking for the name via a GET request resulting in arbitrary code execution on the remote machine.

Buffer overflow vulnerability in Easy Address Book Web Server 1.6 version. The exploitation of this vulnerability could allow an attacker to send a very long username string to /searchbook.ghp, asking for the name via a POST request, resulting in arbitrary code execution on the…

Efs Software Easy Chat Server Version 3.1 was discovered to contain a DLL hijacking vulnerability via the component TextShaping.dll. This vulnerability allows attackers to execute arbitrary code via a crafted DLL.

Easy Chat Server 3.1 contains a denial of service vulnerability that allows remote attackers to crash the application by sending oversized data in the message parameter. Attackers can establish a session via the chat.ghp endpoint and then send a POST request to body2.ghp with an…

An issue was discovered in EFS Easy Chat Server 3.1. There is a buffer overflow via a long body2.ghp message parameter.

register.ghp in EFS Software Easy Chat Server versions 2.0 to 3.1 allows remote attackers to discover passwords by sending the username parameter in conjunction with an empty password parameter, and reading the HTML source code of the response.

register.ghp in EFS Software Easy Chat Server versions 2.0 to 3.1 allows remote attackers to reset arbitrary passwords via a crafted POST request to registresult.htm.

Easy Chat Server, in its 3.1 version and before, does not sufficiently encrypt user-controlled inputs, resulting in a Cross-Site Scripting (XSS) vulnerability stored via /registresult.htm (POST method), in the Icon parameter. The XSS is loaded from /users.ghp.

Easy Chat Server, in its 3.1 version and before, does not sufficiently encrypt user-controlled inputs, resulting in a Cross-Site Scripting (XSS) vulnerability stored via /body2.ghp (POST method), in the mtowho parameter.

Easy Chat Server, in its 3.1 version and before, does not sufficiently encrypt user-controlled inputs, resulting in a Cross-Site Scripting (XSS) vulnerability stored via /registresult.htm (POST method), in the Resume parameter. The XSS is loaded from /register.ghp.

Stored Cross-Site Scripting in Easy Address Book Web Server 1.6 version, through the users_admin.ghp file that affects multiple parameters such as (firstname, homephone, lastname, lastname, middlename, workaddress, workcity, workcountry, workphone, workstate, workzip). This…

Vulnerability in Easy Address Book Web Server 1.6 version, affecting the parameters (firstname, homephone, lastname, middlename, workaddress, workcity, workcountry, workphone, workstate and workzip) of the /addrbook.ghp file, allowing an attacker to inject a JavaScript payload…

chat.ghp in Easy Chat Server 1.2 allows remote attackers to cause a denial of service (server crash) via a long username parameter, possibly due to a buffer overflow. NOTE: it was later reported that 2.2 is also affected.

Stack-based buffer overflow in EFS Software Easy File Sharing FTP Server 2.0 allows remote attackers to execute arbitrary code via a long argument to the PASS command. NOTE: the provenance of this information is unknown; the details are obtained from third party information.

Format string vulnerability in Easy File Sharing (EFS) Web Server 3.2 allows remote attackers to cause a denial of service (server crash) and possibly execute arbitrary code via format string specifiers in the query string argument in an HTTP GET request.

Easy File Sharing (EFS) Easy Address Book 1.2, when run on an NTFS file system, allows remote attackers to read arbitrary files under the web root by appending "::$DATA" to the end of an HTTP GET request, which accesses the alternate data stream.

Easy File Sharing (EFS) Web Server 4.0, when running on an NTFS file system, allows remote attackers to read arbitrary files under the web root by appending "::$DATA" to the end of a HTTP GET request, which accesses the alternate data stream.

Format string vulnerability in Easy Address Book Web Server 1.2 allows remote attackers to cause a denial of service (crash) or "compromise the server" via encoded format string specifiers in the query string.
