4.3
CVSS v3.1
Official Description
Netscape 7.0 allows remote attackers to cause a denial of service (crash) via a web page with an invalid regular expression argument to the JavaScript reformatDate function.
Technical Analysis
CVE-2003-1419 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-2003-1419. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
