CVE-2006-2220

MEDIUMCVSS v2 · 5.05.0—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 5.0 — v2 rates that MEDIUM (v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; v2 has no CRITICAL band). Vector AV:N/AC:L/Au:N/C:P/I:N/A:N. CVSS v2 is an older, coarser metric than v3.1/v4.0 (no Scope, no User Interaction, no Attack Requirements), so it is not directly comparable to a v3 or v4 score. NVD has never re-scored this record under v3. EPSS predicts 1.3% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

No fix has been recorded since the CVE record was published in 2007 — isolate the affected system (restrict network access to it, for example with a firewall, or keep it off the internet) or retire the product.

phpBB 2.0.20 does not properly verify user-specified input variables used as limits to SQL queries, which allows remote attackers to obtain sensitive information via a negative LIMIT specification, as demonstrated by the start parameter to memberlist.php, which reveals the SQL query in the resulting error message.

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).

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".

Data Freshness Timeline

(refreshed 8× in last 7d / 14× 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 78 of 84 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. 22 repeat rows among the latest 100 are merged into the row they repeat. The 6 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

What is CVE-2006-2220?
CVE-2006-2220 is a medium-severity vulnerability; its CVE record was published on February 8, 2007. phpBB 2.0.20 does not properly verify user-specified input variables used as limits to SQL queries, which allows remote attackers to obtain sensitive information via a negative LIMIT specification, as demonstrated by the start parameter to memberlist.php, which reveals the SQL query in the…
When was CVE-2006-2220 made public?
CVE-2006-2220 was made public on May 5, 2006: that is the date its CVE record's CNA, MITRE Corporation, gives for when the vulnerability was made public. The CVE record itself was published on February 8, 2007. 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-2006-2220 actively exploited?
CVE-2006-2220 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 1.3% probability of exploitation in the next 30 days (70th percentile of EPSS-scored CVEs).
How do I remediate CVE-2006-2220?
No fix for CVE-2006-2220 has been recorded since its CVE record was published in 2007, 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.
