Routine

LOW 3.1UPGRADE

CVE-2025-59270 is a low-severity flaw (CVSS 3.1) affecting pspas. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

psPAS PowerShell module does not explicitly enforce TLS 1.2 within the 'Get-PASSAMLResponse' function during the SAML authentication process. An unauthenticated attacker in a 'Man-in-the-Middle' position could manipulate the TLS handshake and downgrade TLS to a deprecated protocol. Fixed in 7.0.209.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

pspete pspas UPGRADE

Affected: >= 6.4.85 and < 7.0.209

Fixed in: 7.0.209

Safe to downgrade to: a release before 6.4.85

1. Check installed version

apt-cache policy pspas || rpm -q pspas || pspas --version

2. UPGRADE to 7.0.209 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade pspas

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade pspas

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 6.4.85 (Debian / Ubuntu)

apt-cache madison pspas sudo apt install pspas=<VERSION_BEFORE_6.4.85> sudo apt-mark hold pspas

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list pspas sudo dnf downgrade pspas-<VERSION_BEFORE_6.4.85> sudo dnf versionlock add pspas

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
