3DescriptionNVD
A flaw has been found in opensourcepos Open Source Point of Sale up to 3.4.2. Impacted is the function Login of the file app/Models/Employee.php of the component Employee Login. This manipulation causes use of weak hash. Remote exploitation of the attack is possible. The attack is considered to have high complexity. The exploitability is considered difficult. The actual existence of this vulnerability is currently in question. The vendor explains: "[T]he code is still there to allow the upgrade path to work. The default password is initially seeded with the old hash function, but then migrated to a newer one after login. [T]he hash version check might be cleaned up in the future. Currently it's not actively in use as any password change will use a newer hash function."
AnalysisAI
Weak password hashing in opensourcepos Open Source Point of Sale through version 3.4.2 exposes a legacy code path in the Employee Login component (app/Models/Employee.php) that retains an older, cryptographically weak hash function. The vendor has disputed the severity of this issue, clarifying that the weak hash function persists solely to support an upgrade migration path - default-seeded passwords use the legacy hash but are migrated to a stronger algorithm upon first login, meaning actively managed accounts on updated installations face reduced practical exposure. …
