CWE-119Published: February 18, 2010· Updated: Jun 16, 2026
Official Description
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.
Technical Analysis
CVE-2010-0416 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2010-0416. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
