CVE-2020-4177 is a security vulnerability discovered in IBM Security Guardium versions 10.5, 10.6, 11.0, and 11.1. The vulnerability was disclosed on June 1, 2020, and involves the presence of hard-coded credentials that the system uses for inbound authentication, outbound communication to external components, or encryption of internal data (IBM Security Bulletin).

The vulnerability has been assigned a CVSS Base score of 6.8 with a vector of CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N. This scoring indicates that the vulnerability is network exploitable but requires high attack complexity, needs no privileges, requires no user interaction, has changed scope, and can result in high confidentiality impact but no integrity or availability impact (IBM Security Bulletin).

The presence of hard-coded credentials in IBM Security Guardium creates a security risk where unauthorized users could potentially gain access to sensitive system functions or data. The vulnerability specifically impacts the confidentiality of the system, with potential exposure of internal data or communication channels (IBM Security Bulletin).

The vulnerability requires high attack complexity (AC:H) and is network accessible (AV:N). No specific instances of exploitation in the wild were reported in the available sources (IBM Security Bulletin).

IBM has released security fixes for all affected versions: Security Guardium 10.5 (SqlGuard_10.0p535_Bundle_Jul-16-2020), 10.6 (SqlGuard_10.0p650_Bundle_Jun-01-2020), 11.0 (SqlGuard_11.0p30_Bundle_Aug-25-2020), and 11.1 (SqlGuard_11.0p115_Bundle_May-19-2020). No workarounds are available, making patch installation the only mitigation option (IBM Security Bulletin).
