CVE-2004-2549

Status: ModifiedMedium (5)—💥 Exploit

Nortel Wireless LAN (WLAN) Access Point (AP) 2220, 2221, and 2225 allow remote attackers to cause a denial of service (service crash) via a TCP request with a large string, followed by 8 newline characters, to (1) the Telnet service on TCP port 23 and (2) the HTTP service on TCP port 80, possibly due to a buffer overflow.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
Base score: 5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 10%
Percentile among all scored CVEs: 96
Score date: 10/7/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
