Is CVE-2008-0455 automatically exploitable on my domain?

Not necessarily. ThreatPort treats CVE-2008-0455 as a risk signal that must be connected to observed external assets, detected technologies, and reachable services.

What does ThreatPort check for CVE-2008-0455?

ThreatPort looks for public asset evidence, service fingerprints, CVE-linked technology signals, exposed endpoints, weak DNS/TLS posture, and remediation context.

Should this replace vendor advisories?

No. Use vendor advisories and official patches for final remediation decisions; use ThreatPort to find externally visible exposure and prove cleanup.

CVE-2008-0455 Http Server exposure check

From CVE Record to External Exposure

Cross-site scripting (XSS) vulnerability in the mod_negotiation module in the Apache HTTP Server 2.2.6 and earlier in the 2.2.x series, 2.0.61 and earlier in the 2.0.x series, and 1.3.39 and earlier in the 1.3.x series allows remote authenticated users to inject arbitrary web script or HTML by uploading a file with a name containing XSS sequences and a file extension, which leads to injection within a (1) "406 Not Acceptable" or (2) "300 Multiple Choices" HTTP response when the extension is omitted in a request for the file.

Http Server vulnerability should be triaged by matching the affected vendor and product to live, internet-facing assets rather than treating the CVE as an abstract feed item. ThreatPort focuses on the first question that budget-constrained IT leaders and CISOs ask: what can an outside observer find today, how severe is it, and what should be fixed first?

What ThreatPort Checks

Identify externally reachable services that appear related to Apache Http Server.

Map detected technologies to CVE-2008-0455, severity context, and practical remediation priority.

Check TLS, DNS, headers, exposed panels, stale endpoints, and service fingerprints from a public attacker perspective.

Produce a concise scorecard first, then unlock deeper AI pentest evidence and PDF reporting when remediation planning begins.

The output is intentionally practical: ownership clues, risk context, remediation hints, and repeatable evidence that can be shared with technical teams or leadership. It is not positioned as magic compliance automation or a replacement for human security judgment.

Lean security teams rarely need another broad vulnerability list. They need to know whether an exposed endpoint, an expired certificate, a weak DNS setting, or a CVE-linked service is likely to affect the systems they actually run. ThreatPort scans from the outside in, ranks what it finds by real reachability rather than raw CVSS, and hands back evidence a team can act on the same day.

Route-Specific Evidence Profile

CVE-2008-0455 affects Apache Http Server, a CWE-79 weakness. Disclosed 2008-01-25. This page exists to answer one question: is anything you own externally reachable and running it.

Assets This Page Should Care About

Public domains Subdomains Externally reachable web apps TLS endpoints DNS records

Signals Worth Prioritizing

Forgotten subdomains

Weak DNS or email controls

Outdated services

Risky headers

What Should Be Reviewed First in This Context?

For teams running Apache Http Server, the first step is to validate internet-facing assets with business relevance instead of producing a generic vulnerability list.
