HIGHCVSS v2 · 7.57.5
EchelonGraph scoreLOW confidence

“—” beside the score: it is equal to NVD's CVSS v2 base score.

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 7.5 — NVD rates that HIGH (NVD's v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; no CRITICAL band). Vector AV:N/AC:L/Au:N/C:P/I:P/A:P. 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 11% exploitation probability in the next 30 days; it does not lift the v2 base. EchelonGraph's fixed weight for EG-KEV Tier 2 (Weaponized) sets EG Risk's exploitation input, not EPSS. Confidence: LOW.

Buffer overflow in the Unescape function in common/util/hxurl.cpp and player/hxclientkit/src/CHXClientSink.cpp in Helix Player 1.0.6 and RealPlayer allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a URL argument containing a % (percent) character that is not followed by two hex digits.

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).

Exploitation public PoC (exploit code on record) · Automatable no (CISA's BOD 26-04 default) · Technical impact total (CISA's BOD 26-04 default). 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".

In CISA KEV no (CISA's KEV catalog) · Automatable no (CISA's BOD 26-04 default) · Technical impact total (CISA's BOD 26-04 default). Where an input reads “CISA's BOD 26-04 default”, no one has published it for this CVE, and CISA's implementation guidance says: “If “Automatable” and “Technical Impact” information items about a CVE ID are not available and the CVE ID is not in the KEV Catalog, CISA will treat its values as “no” and “total,” respectively, until CISA or a third party provides metadata about the CVE ID. CISA will always provide the Vulnrichment data for a CVE ID listed in the KEV Catalog.” Whether your system is publicly exposed is yours to answer. BOD 26-04 binds US Federal Civilian Executive Branch agencies; for anyone else it is CISA's published timeline, a reference rather than an obligation. The directive · how EchelonGraph applies it

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.

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. 18 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(4)

What is CVE-2010-0416?
CVE-2010-0416 is a high-severity vulnerability; its CVE record was published on February 18, 2010. Buffer overflow in the Unescape function in common/util/hxurl.cpp and player/hxclientkit/src/CHXClientSink.cpp in Helix Player 1.0.6 and RealPlayer allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a URL argument containing a % (percent)…
When was CVE-2010-0416 made public?
CVE-2010-0416 was made public on February 9, 2010: that is the date its CVE record's CNA, Red Hat, Inc., gives for when the vulnerability was made public. The CVE record itself was published on February 18, 2010. EchelonGraph's copy of the record carries a last-modified date of April 29, 2026; the record at its source may have been updated since.
Is CVE-2010-0416 actively exploited?
CVE-2010-0416 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 11% probability of exploitation in the next 30 days (95th percentile of EPSS-scored CVEs).
How do I remediate CVE-2010-0416?
A fix for CVE-2010-0416 is available: update to the fixed version the vendor names in its advisory.
