Detailsinfo

A vulnerability has been found in Chew Kean Ho Software Actualizer up to 1.2.0 and classified as problematic. This vulnerability affects an unknown code of the file Shell/debian-minbase-install.sh of the component Password Loops. The manipulation with an unknown input leads to a hard-coded password vulnerability. The CWE definition for the vulnerability is CWE-259. The product contains a hard-coded password, which it uses for its own inbound authentication or for outbound communication to external components. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

(Holloway) Chew, Kean Ho's Actualizer v1.2.0 and earlier contains a fail-open password validation vulnerability in the Alpha user and root user password loops of Shell/debian-minbase-install.sh. The installer invokes mkpasswd to generate yescrypt password hashes but does not check the command's return value and unconditionally accepts the result. If mkpasswd fails to generate a yescrypt hash, for example because an incompatible mkpasswd implementation or an environment without yescrypt support is used, the resulting password hash variable can be empty and the build proceeds. The resulting image can therefore contain empty password fields for the root and alpha accounts, potentially permitting passwordless authentication depending on the authentication configuration.

The advisory is available at github.com. This vulnerability was named CVE-2026-85649 since 09/04/2026. The exploitation appears to be easy. Local access is required to approach this attack. Additional levels of successful authentication are needed for exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1078.001 by the MITRE ATT&CK project.
