D-Link DWL-2600AP Access Point vulnerability
D-Link DWL-2600AP access point contains an authenticated command injection vulnerability in the configuration save functionality, allowing shell command execution through unsanitized parameters.
Verdict
Today item — known-exploited.
An authenticated attacker can inject arbitrary shell commands via the admin.cgi configuration backup or download server IP parameters, achieving remote code execution on the affected access point with high exploitability.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
2 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2023-06-29).
Probability (EPSS)
EPSS 0.95803 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: D-Link, DWL-2600AP Access Point. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-78 OS Command Injection — weakness family: Injection.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I authenticate to the web interface using valid credentials.
Business
Access point requires credential compromise or default credentials to be exploited.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I inject shell metacharacters into the configBackup or downloadServerip parameters during configuration save operations.
Business
Lack of input validation on administrative functions creates execution risk.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute arbitrary commands with the privileges of the web server process on the access point.
Business
Attacker gains control of network infrastructure, potentially compromising all connected devices and network traffic.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
