CVE-2013-7331 Microsoft Internet Explorer: information leak
In plain words: The program reveals information it should keep private. Leaked secrets — tokens, passwords or memory contents — that help a bigger attack.
Confirmed exploited by CISA on · US federal patch deadline Jun 15, 2022
What to do
- Install Microsoft's security update for Internet Explorer. If no update exists, follow the vendor's workaround or stop using the product until one ships.
- Let the browser auto-update and relaunch it when it asks — the fix is not active until you do.
- Keep extensions to a minimum and remove ones you do not recognise.
- Stop using Internet Explorer and any browser that no longer gets updates.
Who is affected
Could reach you. This one is aimed at devices or apps of the kind people own.
What's at risk: A malicious or hacked website can be enough. Browser bugs are often the first step in a longer attack on the whole computer or phone.
