CVE-2026-116054 SH3 Informática Ltda CVE debrief

Who should care

Defenders responsible for the SH3 system, specifically those managing the Módulo de Gestão/Módulo de Arrecadação component, should assess exposure and prioritize upgrading to version 2026.0.2.0.

Why it matters

The CVE-2026-116054 vulnerability in SH3's Módulo de Gestão/Módulo de Arrecadação component requires attention from defenders due to its weak password hash with insufficient computational effort. While the high complexity of exploitation and low CVSS score indicate a low-priority issue, upgrading to version 2026.0.2.0 is still recommended.

• Defenders need to verify if the system is vulnerable and upgrade to version 2026.0.2.0
• The weak password hash may require additional security measures to prevent exploitation
• The high complexity of exploitation reduces the immediate risk but does not eliminate it

Technical summary

The vulnerability affects the SH3 Módulo de Gestão/Módulo de Arrecadação component, allowing for a weak password hash with insufficient computational effort. The attack is possible to be carried out remotely with high complexity. The exploit has been disclosed publicly and may be used. Upgrading to version 2026.0.2.0 mitigates this issue. Defenders should prioritize upgrading the affected component. Due to the low CVSS score and difficulty in exploiting this vulnerability, it is considered a low-priority issue but still requires attention.
