DescriptionCVE.org

A 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.

AnalysisAI

Least privilege violation in the D-Link DGS-1100-08PD managed switch firmware version 1.00.006 allows remote unauthenticated attackers to achieve low-integrity impact through improper processing of the Boa web server configuration file /etc/boa.conf via the device's web interface. The CVSS 4.0 score is 2.9 (Low), reflecting high attack complexity (AC:H) and constrained impact (VI:L only), though a publicly available proof-of-concept lowers the barrier for skilled attackers. …

Vulnerability AssessmentAI

Exploitation CVSS PR:N confirms no authentication is required to attempt exploitation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The overall risk is low, corroborated by the CVSS 4.0 base score of 2.9. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A remote attacker with knowledge of the specific exploitation technique - or armed with the publicly available proof-of-concept linked on Notion (https://www.notion.so/D-link-DGS-1100-08PD-v1-00-006-3670ed14e5cb80848bc4e3129dfafa29) - sends crafted HTTP requests to the DGS-1100-08PD web interface targeting the /etc/boa.conf processing path. By satisfying the high-complexity preconditions (e.g., specific request sequencing, race condition, or parameter manipulation), the attacker triggers a least privilege violation that allows low-level modification or partial disclosure of configuration state beyond what the web interface should permit. …
Remediation No vendor-released patch or specific fixed firmware version was identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
