Alert meAnalysisAIv1 – Mar 12, 2026
Authenticated users can exploit a path traversal vulnerability in the SFX2100 firmware's logging interface to enumerate arbitrary files on the system through directory traversal in the file parameter. Public exploit code exists for this medium-severity flaw, and no patch is currently available, leaving affected organizations reliant on access controls to mitigate risk. The vulnerability allows attackers with valid credentials to confirm file existence through backup operation responses, potentially exposing sensitive system information.

2DescriptionCVE.org
A path traversal vulnerability exists in the /IDC_Logging/checkifdone.cgi script in International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver Web management portal version 101. An authenticated attacker can manipulate the file parameter to traverse directories and enumerate arbitrary files on the underlying filesystem. Due to the insecure perl file path handling function in use, a authenticated actor is able to preform directory traversal, with the backup endpoint confirming a file exists by indicating that a backup operation was successful or when using the path of a non existent file, the returned status is failed.
Executive ViewAI
CVE-2026-28769 presents notable security risk, a path traversal vulnerability rated CVSS 6.5. This could allow unauthorized file access. Proof-of-concept code is publicly available. Organizations should apply vendor updates when available and monitor for exploitation.
Apply vendor patch. If patching is delayed: restrict file access via WAF, implement allowlists.
