CVE-2026-5310 Details
Description
A vulnerability was identified in Enter Software Iperius Backup up to 8.7.2. This impacts an unknown function of the file IperiusAccounts.ini. Such manipulation leads to use of hard-coded cryptographic key . The attack must be carried out locally. This attack is characterized by high complexity. The exploitability is said to be difficult. The exploit is publicly available and might be used. Upgrading to version 8.7.4 will fix this issue. It is suggested to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
A vulnerability exists in Enter Software Iperius Backup versions prior to 8.7.2, where sensitive user credentials are stored in the IperiusAccounts.ini file. The encryption uses a hard-coded key, derived from a static Italian-language error message, applied uniformly across all installations. This key allows for offline decryption of credentials, including those for Domain Administrator, SQL Database, SMTP, FTP, and Cloud Storage accounts. The vulnerability requires local access to the configuration file, but the decryption can be performed using a publicly available Python script or by exploiting the application as a Decryption Oracle.
Users are advised to upgrade to Iperius Backup version 8.7.4, which addresses this vulnerability by implementing a more secure encryption method for credentials. The update is available on the Iperius Backup website.
