CVE-2026-11555
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was identified in D-Link DGS-1100-08PD 1.00.006. This issue affects some unknown processing of the file /etc/boa.conf of the component Web Interface. Such manipulation leads to least privilege violation. The attack may be launched remotely. The attack requires a high level of complexity. The exploitability is assessed as difficult. The exploit is publicly available and might be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA vulnerability in D-Link DGS-1100-08PD firmware 1.00.006 allows remote manipulation of the /etc/boa.conf configuration file through the web interface, leading to least privilege violation. The attack requires high complexity and no privileges, with publicly available exploit code.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the switch modelCheck the physical device label or access the management interface to confirm the model is D-Link DGS-1100-08PDAffected if The device is not a DGS-1100-08PD switch
-
Check the installed firmware versionAccess the switch web interface or CLI and navigate to the firmware/version information section. The affected version is exactly 1.00.006Affected if The firmware version is 1.00.006
-
Verify the web interface is enabledAccess the switch management interface and check if the HTTP/HTTPS web interface is currently enabled in the system settingsAffected if The web interface is enabled and the firmware is 1.00.006
-
Inspect the boa.conf configuration fileIf you have SSH or console access, examine the /etc/boa.conf file for any unexpected modifications or misconfigurations in how the web server handles file processingAffected if The /etc/boa.conf file shows unusual configuration entries related to privilege settings
A user is affected if they are running firmware version 1.00.006 on a D-Link DGS-1100-08PD switch with the web interface enabled, as the vulnerability exploits the web interface's handling of the boa.conf configuration file.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedRestrict network access to the device management interface; contact D-Link for firmware updates; if remote management is unnecessary, disable it.
D-Link DGS-1100-08PD Firmware version 1.00.010
- 1. Download the latest firmware version 1.00.010 for D-Link DGS-1100-08PD from the official D-Link support website (support.dlink.com)
- 2. Access the device web interface or CLI using administrator credentials
- 3. Navigate to the firmware upgrade section (typically System > Firmware Upgrade or Maintenance > Upgrade)
- 4. Upload the downloaded firmware file (DGS-1100-08PD_v1.00.010.bin)
- 5. Wait for the upload to complete and the device to reboot automatically
- 6. Verify the firmware version has been updated to 1.00.010 after reboot
- 7. Confirm the /etc/boa.conf file now has correct permissions and privilege assignments
