CVE-2013-3896
HIGH ⌖ ON CISA KEV · EXPLOITEDA legacy Microsoft Silverlight vulnerability (CVE-2013-3896) allowed remote attackers to extract sensitive data via pointer validation flaws.
Microsoft Silverlight, a discontinued platform, suffered an information disclosure flaw where improper pointer validation let attackers read sensitive data. DIBs must care because legacy software like this is often left unpatched, creating long-standing exposure to known exploits. The takeaway is to retire unsupported platforms and patch known CVEs before they hit the KEV list.
Shame score — A known, unpatched vulnerability in legacy software that was actively exploited in the wild, showing negligence in maintaining outdated platforms.
▸ RECOMMENDED ACTION Actively exploited (CISA KEV) — remediate now, ahead of your normal patch cycle.
Microsoft Silverlight does not properly validate pointers during access to Silverlight elements, which allows remote attackers to obtain sensitive information via a crafted Silverlight application.
