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 shellcode and ROP gadgets to achieve code execution in the application context.

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 excessively large message parameter value to cause the service to crash.

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.

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.

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.

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) Webserver 1.25 allows remote attackers to cause a denial of service (CPU consumption or crash) via many large HTTP requests.

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.

Absolute path traversal vulnerability in Easy File Sharing (EFS) Web Server 3.2 allows remote registered users to execute arbitrary code by uploading a malicious file to the Windows startup folder.

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 allows a remote attacker to store a malicious JavaScript payload in the application to be executed when the page is loaded, resulting in an integrity impact.

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 specially designed to run when the application is loaded

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 remote machine.

Easy Chat Server 2.1 stores sensitive information under the web root with insufficient access control, which allows remote attackers to download certain files via direct requests to files such as (1) ServerKey.pem and (2) AcceptIP.txt. NOTE: The provenance of this information is unknown; the details are obtained solely from third party information.

Cross-site scripting (XSS) vulnerability in Easy File Sharing (EFS) Web Server 4.0 allows remote attackers to inject arbitrary web script or HTML via the (1) author, (2) content, or (3) title parameters when posting a forum thread. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Cross-site scripting (XSS) vulnerability in Easy File Sharing (EFS) Web Server 3.2 allows remote attackers to inject arbitrary web script or HTML via the Description field in creating a folder or uploading a file.

chat.ghp in Easy Chat Server 1.2 allows remote attackers to add a large number of fake users, then eventually cause a denial of service (server crash).
