7.2
CVSS v3.1
Official Description
Buffer overflow in the nss_ldap.so.1 library for Sun Solaris 8 and 9 may allow local users to gain root access via a long hostname in an LDAP lookup.
Technical Analysis
CVE-2003-1055 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-2003-1055. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
