Can you explain this vulnerability to me?

CVE-2018-25232 is a denial of service vulnerability in Softros LAN Messenger version 9.2. It occurs when a local attacker inputs an excessively long stringβ€”specifically, a buffer of 2000 charactersβ€”into the custom log files location field. When the attacker clicks the OK button after entering this long string, the application crashes due to improper input validation of the log file path parameter.

This vulnerability arises because the application does not properly validate or sanitize the input for the log file location, allowing the attacker to cause a crash by supplying an overly long string.


How can this vulnerability impact me? :

This vulnerability can impact you by causing a denial of service condition in the Softros LAN Messenger application. Specifically, a local attacker can crash the application by supplying a specially crafted input to the log files location field, disrupting communication within the application.

Since Softros LAN Messenger is used for intra-office communication, crashing the application can interrupt messaging, file transfers, and other collaboration features, potentially affecting productivity and communication within an organization.

The CVSS v4.0 base score of 6.8 indicates a moderate severity with high impact on availability, meaning the main impact is the loss of availability of the messaging service.


How can this vulnerability be detected on my network or system? Can you suggest some commands?

This vulnerability can be detected by attempting to reproduce the crash condition on the Softros LAN Messenger application. Specifically, a local user can test the logging feature by inputting an excessively long string (2000 characters) into the custom log files location field.

A proof-of-concept method involves using a script to generate a payload of 2000 'A' characters, copying this payload to the clipboard, and then pasting it into the Log Files Location custom path parameter in the application's Logging settings. Clicking the OK button will trigger the crash if the vulnerability is present.

The steps to detect the vulnerability include:

  • Run a script (e.g., a Python script) that creates a file containing 2000 'A' characters.
  • Copy the content of this file to the clipboard.
  • Open Softros LAN Messenger and navigate to the Logging settings.
  • Select 'Custom Location' for Log Files Location and paste the clipboard content.
  • Click the OK button and observe if the application crashes.

What immediate steps should I take to mitigate this vulnerability?

To mitigate this vulnerability, immediate steps include restricting local user access to the logging configuration settings in Softros LAN Messenger to prevent input of excessively long strings in the custom log files location field.

Additionally, ensure that users are educated not to input unusually long or malformed paths in the logging settings.

If available, update the Softros LAN Messenger software to a version where this vulnerability is fixed or patched.

As a temporary workaround, avoid using the custom log files location feature until a patch or update is applied.
