How severe is CVE-2008-4250?

CVE-2008-4250 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which products are affected by CVE-2008-4250?

Affected package information for CVE-2008-4250 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2008-4250?

No patch has shipped for CVE-2008-4250 yet — track the microsoft windows 2000 advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2008-4250 across my infrastructure?

Inventory every microsoft windows 2000 deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2008-4250 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2008-4250?

O3 detects and blocks CVE-2008-4250 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2008-4250 actively exploited in the wild?

Yes. There are 14 known exploit references for CVE-2008-4250, including 6 documented proof-of-concept exploits on Exploit-DB and 8 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2008-4250?

CVE-2008-4250 has an EPSS (Exploit Prediction Scoring System) score of 98.8%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2008-4250 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2008-4250 (Microsoft Windows Buffer Overflow Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2026-05-20. CISA required all US federal civilian agencies to remediate this vulnerability by 2026-06-03. The required action was: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2008-4250?

CVE-2008-4250 is classified as Code Injection (CWE-94), Buffer Overflow (CWE-119). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2008-4250?

CVE-2008-4250 affects microsoft windows 2000; microsoft windows server 2003; microsoft windows server 2008; microsoft windows vista, and 1 more product(s). Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2008-4250 published, and has it been updated?

CVE-2008-4250 was published on October 23, 2008 and was last updated on June 16, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

98.8%probability of exploitation in next 30 days

Very High Risk100th percentile0.00%

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

The Server service in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, Server 2008, and 7 Pre-Beta allows remote attackers to execute arbitrary code via a crafted RPC request that triggers the overflow during path canonicalization, as exploited in the wild by Gimmiv.A in October 2008, aka "Server Service Vulnerability."
