CVE-2024-54852 is a critical-severity flaw (CVSS 9.8) affecting teedy. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

When LDAP connection is activated in Teedy versions between 1.9 to 1.12, the username field of the login form is vulnerable to LDAP injection. Due to improper sanitization of user input, an unauthenticated attacker is then able to perform various malicious actions, such as creating arbitrary accounts and spraying passwords.

sismics teedy UPGRADE

Affected: >= 1.9 and <= 1.12

Fixed in: newer than 1.12

Safe to downgrade to: a release before 1.9

1. Check installed version

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

2. UPGRADE to newer than 1.12 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade teedy

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 1.9 (Debian / Ubuntu)

apt-cache madison teedy sudo apt install teedy=<VERSION_BEFORE_1.9> sudo apt-mark hold teedy

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

dnf --showduplicates list teedy sudo dnf downgrade teedy-<VERSION_BEFORE_1.9> sudo dnf versionlock add teedy

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.
