VAR-200803-0168
Vulnerability from variot - Updated: 2025-04-10 20:45cgi-bin/setup_virtualserver.exe on the Belkin F5D7230-4 router with firmware 9.01.10 allows remote attackers to cause a denial of service (control center outage) via an HTTP request with invalid POST data and a "Connection: Keep-Alive" header. The Belkin F5D7230-4 Wireless G Router is prone to a denial-of-service vulnerability. Attackers can exploit this issue to deny access to the device's control center for legitimate users. Belkin F5D7230-4 running firmware 9.01.10 is vulnerable; other devices and firmware versions may also be affected. ----------------------------------------------------------------------
A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched.

TITLE: Belkin Wireless G Router Security Bypass and Denial of Service
SECUNIA ADVISORY ID: SA29345
VERIFY ADVISORY: http://secunia.com/advisories/29345/
CRITICAL: Less critical
IMPACT: Security Bypass, DoS
WHERE:
From local network
OPERATING SYSTEM: Belkin Wireless G Router http://secunia.com/product/6130/
DESCRIPTION: Some security issues and a vulnerability have been reported in the Belkin Wireless G Router, which can be exploited by malicious people to bypass certain security restrictions or cause a DoS (Denial of Service).
1) An error in the implementation of authenticated sessions can be exploited to gain access to the router's control panel by establishing a session from a previously authenticated IP address.
2) An error exists within the enforcing of permissions in cgi-bin/setup_dns.exe. This can be exploited to perform restricted administrative actions by directly accessing the vulnerable script.
3) An error exists in the cgi-bin/setup_virtualserver.exe script when processing HTTP POST data.
The security issues and the vulnerability are reported in model F5D7230-4, firmware version 9.01.10.
SOLUTION: Restrict network access to the router's web interface.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
