CVE-2025-52222: D-Link DI-8003 v16.07.26A1, DI-8500 v16.07.26A1; DI-8003G v17.12.21A1, DI-8200G v17.12.20A1, DI-8200 v16.07.26A1, DI-8400 v16.07.26A1, DI-80

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

D-Link DI-8003 v16.07.26A1, DI-8500 v16.07.26A1; DI-8003G v17.12.21A1, DI-8200G v17.12.20A1, DI-8200 v16.07.26A1, DI-8400 v16.07.26A1, DI-8004w v16.07.26A1, DI-8100 v16.07.26A1, and DI-8100G v17.12.20A1 were discovered to contain a buffer overflow via the rd_en, rd_auth, rd_acct, http_hadmin, http_hadminpwd, rd_key, and rd_ip parameters in the radius_asp function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.

Weakness class (CWE)

CWE-120 · Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

CVSS vector

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Root cause

When data is copied, the source length is not compared with the size of the destination buffer. Excess data overwrites adjacent memory.
