CVE-2014-1762: Microsoft Internet Explorer remote code execution and sandbox bypass

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: medium.

high priorityRemote, unauthenticated code execution with sandbox bypass in a widely deployed browser, with a demonstrated exploit and very high EPSS score, though no KEV listing and thin technical detail.

What it is

CVE-2014-1762 is an unspecified vulnerability in Microsoft Internet Explorer 6 through 11 that lets a remote attacker execute arbitrary code with medium-integrity privileges and bypass a sandbox protection mechanism. The record gives no root cause, affected component or affected version detail beyond the browser range, so defenders must rely on the vendor bulletin rather than the description. It matters because code execution plus sandbox escape weakens the browser's main containment boundary.

Impact

An attacker gains arbitrary code execution at medium integrity and can escape the sandbox protection mechanism, allowing actions beyond what the browser's low-integrity sandbox normally permits. The record does not state whether full system compromise or privilege escalation to high integrity is achievable.

Attack surface

The CVSS vector AV:N/AC:L/Au:N indicates the flaw is reachable over the network with no authentication and no user interaction required by the vector itself. The description says remote attackers trigger it via unknown vectors, so the exact entry point in the browser is not specified.

Exploitation

The flaw was demonstrated by ZDI during the Pwn4Fun competition at CanSecWest 2014, so a working exploit existed at disclosure. It is not listed in CISA KEV, and EPSS shows a 30-day probability of 0.70727 (99.364th percentile), indicating high predicted exploitation activity.

What to do

• Apply the Microsoft fix referenced in security bulletin MS14-035, or upgrade to a supported browser version if the affected Internet Explorer release is no longer patched.
• Retire Internet Explorer 6 through 11 where possible; these versions are end-of-life and no longer receive security updates.
• Enforce sandbox and integrity-level protections and avoid running the browser with elevated privileges.
• Restrict browsing to trusted sites and block known malicious or untrusted content at the network boundary.
• Monitor vendor advisories for updated guidance since the record lacks technical detail on the vulnerable component.

Detection

• Hunt for Internet Explorer processes spawning unexpected child processes or writing to unusual locations, which can indicate sandbox escape or code execution.
• Monitor for browser crashes or exploit-like behavior in IE versions 6 through 11 on endpoints that still run them.
• Review proxy and network logs for known exploit delivery patterns targeting IE during the 2014 disclosure window and later.
• Alert on attempts to elevate from medium-integrity browser processes to higher-integrity operations.
