D-Link DAP-2695 CVE-2025-12295

Exploitation requires authenticated administrative access to the DAP-2695 management plane (CVSS PR:H) and interaction with the Firmware Update Handler, specifically triggering the flawed signature-verification logic in function sub_40C6B8 by supplying a crafted/tampered firmware image. Limiting factors: the attacker must already possess high-privilege credentials (not remote-unauthenticated), the vendor rates exploitation as 'difficult' and 'highly complex' (AC:H), and the flaw affects only the specific EOL DAP-2695 2.00RC13 firmware - reducing realistic exposure to environments where an attacker has already compromised device admin access.

Real-world risk is LOW-to-MODERATE despite a CVSS 4.0 base score of 6.6. The CVSS 4.0 vector (AV:N/AC:H/PR:H/UI:N/VC:H/VI:H/VA:H) shows that while the attack is network-reachable, it carries both HIGH attack complexity (AC:H - vendor describes exploitation as 'difficult' and 'highly complex') and HIGH privilege requirements (PR:H), meaning the attacker must already hold administrative/authenticated access to the device management plane. These two factors sharply constrain practical exploitation. EPSS corroborates this low urgency at 0.45% (37th percentile), indicating no meaningful signal of broad opportunistic exploitation. This is NOT in CISA KEV, so there is no confirmed active exploitation; however, publicly available exploit code exists (E:P in the vector, plus an NVD-referenced PoC on GitHub), which raises the floor on who can attempt it. No SSVC decision record is provided in the input, so automatable/technical-impact SSVC values cannot be cited. Net: the signals are internally consistent - high impact but high barrier (privileged + complex) - so this is a high-CVSS-impact-but-low-real-risk issue for most defenders, elevated only where attackers already have admin footholds on these specific EOL access points. One caveat to verify: the product is end-of-life (no vendor patch will be issued), which paradoxically keeps residual risk elevated indefinitely on any still-deployed units.

An attacker who has already obtained administrative credentials to a D-Link DAP-2695 management interface crafts a malicious firmware image that fails to properly validate against the device's cryptographic signature check in function sub_40C6B8. The attacker uploads this image through the Firmware Update Handler, and the improper signature verification (CWE-345) allows the tampered firmware to be accepted and flashed, yielding full control of the device. Public exploit code is available, though the vendor rates actual exploitation as difficult/highly complex.
