CVE-2026-93958: D-Link R95 DHMAPI ssi system os command injection
A vulnerability was found in D-Link R95 BE9500_1.00.16. This vulnerability affects the function system of the file /bin/ssi of the component DHMAPI. The manipulation of the argument NTPServer results in os command injection. The attack can be executed remotely. The exploit has been made public and could be used.
Security readout for executives and security teams
Plain-English summary
A flaw in D-Link R95 firmware could let a remote attacker with high privileges run operating-system commands through a time-server setting. Successful exploitation could compromise device data and operation. The supplied record rates it critical and reports a public exploit, but does not establish active attacks or identify a confirmed fix.
Executive priority
Promptly identify affected devices and assign an owner to confirm vendor remediation. Prioritize systems with broadly reachable management interfaces or weak privileged-access controls. Critical reported impact and public exploit availability justify urgent assessment, while the high-privilege prerequisite and absence of documented active exploitation should inform response scope.
Technical view
The supplied record identifies OS command injection through the NTPServer argument reaching the system function in /bin/ssi within DHMAPI. It lists firmware BE9500_1.00.16 and CWE-77/CWE-78. The CVSS 4.0 score is 9.4: network access, low complexity, high privileges, and no user interaction, with high confidentiality, integrity, and availability impacts to vulnerable and subsequent systems.
Likely exposure
Prioritize D-Link R95 devices running BE9500_1.00.16 where an attacker could reach DHMAPI and obtain the required high privileges. Network attackability does not establish internet exposure. A referenced submission title names 1.01B06, creating an unresolved version discrepancy; the bundle does not establish whether that version or other releases are affected.
Exploitation context
The supplied description reports a public exploit, and its references identify a GitHub exploit repository. The CVSS vector includes E:P, indicating proof-of-concept maturity. The bundle marks KEV as false and provides no evidence of active exploitation. Public exploit availability increases concern but does not demonstrate attacks against deployed devices.
Researcher notes
This assessment uses only the supplied bundle; linked pages and exploit contents were not independently reviewed. Exact authentication mechanics, deployment exposure, vendor confirmation, and remediation remain unspecified. The firmware discrepancy limits version certainty. CVSS subsequent-system impacts are reported scoring claims, not demonstrated attack outcomes in the supplied evidence.
Mitigation direction
Check D-Link guidance for confirmed affected versions, available firmware fixes, and supported workarounds; none is identified in the bundle.
As a precaution, restrict management access to trusted administrators and networks where operationally feasible; this is not a confirmed vendor workaround.
Review privileged administrator access and remove unnecessary permissions, given the stated high-privilege exploitation requirement.
Validation and detection
Inventory D-Link R95 devices and record exact firmware versions, prioritizing matches to BE9500_1.00.16.
Confirm DHMAPI reachability and administrative access restrictions through configuration review without attempting exploitation.
Resolve the BE9500_1.00.16 versus 1.01B06 discrepancy using vendor guidance before declaring a device unaffected.
If a vendor fix becomes available, verify installation and confirm its advisory explicitly addresses this CVE.
