4.6
CVSS v3.1
Official Description
Signed integer vulnerability in libnasl in Nessus before 2.0.6 allows local users with plugin upload privileges to cause a denial of service (core dump) and possibly execute arbitrary code by causing a negative argument to be provided to the insstr function as used in a NASL script.
Technical Analysis
CVE-2003-0372 requires local access, meaning attackers must already have a foothold on the target system.
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-2003-0372. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
