CVE-2014-3919Network attack vector

Sensitive-information exposure via embedded malicious script

Published Feb 13, 2020 · Updated Aug 6, 2024

Cross-site scripting in NETGEAR CG3100 firmware before 3.9.2421.13.mp3 V0027 allows remote attackers to expose sensitive information. The published record says only that an unspecified page embeds malicious script content and does not identify the input parameter or rendering operation. Exploitation requires a victim to interact with the crafted content; the documented consequence is sensitive-information exposure.
