PYSEC-2022-42997

Vulnerability from pysec - Published: 2022-12-06 18:15 - Updated: 2023-05-04 04:29

Details

Passeo is an open source python password generator. Versions prior to 1.0.5 rely on the python random library for random value selection. The python random library warns that it should not be used for security purposes due to its reliance on a non-cryptographically secure random number generator. As a result a motivated attacker may be able to guess generated passwords. This issue has been addressed in version 1.0.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.

GHSA-MHHF-VGWH-FW9H

Vulnerability from github – Published: 2022-12-06 21:13 – Updated: 2024-10-09 20:09

Summary

Passeo uses insecure random number generator

Details

Impact

Everyone below v1.0.5 is impacted by this flaw, of confidentiality being at risk due to the password(s) being easily able to be guessed with Passeo's use of the random library. It is recommended to change any passwords made with Passeo before v1.0.5 and upgrade to v1.0.5, and v1.0.5 patches this with the secrets library.

Workarounds

No current workaround available than updating to v1.0.5.
