CVE-2010-0178
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMozilla Firefox before 3.0.19, 3.5.x before 3.5.9, and 3.6.x before 3.6.2, and SeaMonkey before 2.0.4, does not prevent applets from interpreting mouse clicks as drag-and-drop actions, which allows remote attackers to execute arbitrary JavaScript with Chrome privileges by loading a chrome: URL and then loading a javascript: URL.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis browser vulnerability allows malicious web pages to execute arbitrary JavaScript with Chrome privileges by exploiting how applets interpret mouse clicks as drag-and-drop actions, chaining chrome: and javascript: URL loads to bypass security restrictions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Mozilla productOpen the application and go to Help > About (Firefox or SeaMonkey). Alternatively, check the application executable or registry entry for the product name.Affected if The product is either Mozilla Firefox or Mozilla SeaMonkey
-
Determine Firefox version numberIn Firefox, go to Help > About Firefox. The version displayed (e.g., 3.5.7, 3.6, 3.0.17) is the installed version.Affected if The version matches any of: 3.5.x (3.5.1 through 3.5.7), 3.6, 3.0.x (any version up to and including 3.0.17), or legacy versions 0.1 or 0.2
-
Determine SeaMonkey version numberIn SeaMonkey, go to Help > About SeaMonkey. The version displayed (e.g., 2.0.3, 1.1.19) is the installed version.Affected if The version matches any of: 2.0.x (any version up to and including 2.0.3), or 1.x versions (1.0 through 1.1)
-
Verify Java plugin is enabledCheck Firefox/SeaMonkey Add-ons > Plugins section. Look for 'Java Platform SE' or similar Java plugin entry.Affected if The Java plugin is installed and enabled (the vulnerability exploits applet drag-and-drop behavior)
You are affected if you are running Firefox version 3.5.x, 3.6, 3.0.x through 3.0.17, or SeaMonkey 2.0.3 or earlier, and the Java plugin is enabled to handle applets.
