SCO UNIX System V/386 Release 3.2, and other SCO products, installs the home directories (1) /tmp for the dos user, and (2) /usr/tmp for the asg user, which allows other users to gain access to those accounts since /tmp and /usr/tmp are world-writable.
CVE-1999-1138 is a security vulnerability that . Impacting 4 products from sco, from sco, from sco and 1 other, organizations running these solutions should prioritize assessment and patching.
Originally identified in 1993, this vulnerability predates many modern security frameworks and practices. The vulnerability landscape of that era was characterized by different threat models and less mature defense mechanisms compared to contemporary standards.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For sco's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
