No fix has been recorded since the CVE record was published in 2009 — isolate the affected system (restrict network access to it, for example with a firewall, or keep it off the internet) or retire the product.

Multiple cross-site request forgery (CSRF) vulnerabilities in sample code in the XenServer Resource Kit in Citrix XenCenterWeb allow remote attackers to hijack the authentication of administrators for (1) requests that change the password via the username parameter to config/changepw.php or (2) stop a virtual machine via the stop_vmname parameter to hardstopvm.php. NOTE: some of these details are obtained from third party information.

EG Risk 70/100

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

EchelonGraph holds no SSVC assessment of this CVE from CISA: none of these inputs is from Vulnrichment. EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Weakness Classification(1)

MITRE Common Weakness Enumeration — the root-cause categories this CVE belongs to.

Data Freshness Timeline

(refreshed 8× in last 7d / 17× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 80 of 112 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 20 repeat rows among the latest 100 are merged into the row they repeat. The 32 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2009-3759?
CVE-2009-3759 is a high-severity vulnerability; its CVE record was published on October 22, 2009. Multiple cross-site request forgery (CSRF) vulnerabilities in sample code in the XenServer Resource Kit in Citrix XenCenterWeb allow remote attackers to hijack the authentication of administrators for (1) requests that change the password via the username parameter to config/changepw.php or (2)…
When was the CVE record for CVE-2009-3759 published?
The CVE record for CVE-2009-3759 was published on October 22, 2009. That is the record's publication date; the vulnerability itself may have been made public earlier. EchelonGraph's copy of the record carries a last-modified date of April 23, 2026; the record at its source may have been updated since.
Is CVE-2009-3759 actively exploited?
CVE-2009-3759 is not currently on CISA's Known Exploited Vulnerabilities catalog. EchelonGraph's EG-KEV model places it in Tier 2 (Weaponized), which is not evidence of exploitation: Exploit-DB marks a public exploit for it as verified. EchelonGraph does not test whether exploit code works. FIRST EPSS estimates a 2.3% probability of exploitation in the next 30 days (82nd percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2009-3759?
CVE-2009-3759 has a CVSS v3 base score of 8.8 (NVD).
How do I remediate CVE-2009-3759?
No fix for CVE-2009-3759 has been recorded since its CVE record was published in 2009, and EchelonGraph holds no vendor advisory for it. Isolate the affected system (restrict network access to it, for example with a firewall, or keep it off the internet) or retire the product.
