Details

The System extension Install tool in TYPO3 4.0.0 through 4.0.9, 4.1.0 through 4.1.7, and 4.2.0 through 4.2.3 creates the encryption key with an insufficiently random seed, which makes it easier for attackers to crack the key.

GHSA-84C3-J8R2-MCM8

Vulnerability from github – Published: 2024-02-26 20:10 – Updated: 2024-02-26 20:10
VLAI
Summary
@nfid/embed has compromised private key due to @dfinity/auth-client producing insecure session keys
Details

Problem

User sessions in the @nfid/embed SDK with Ed25519 keys are vulnerable due to a compromised private key 535yc-uxytb-gfk7h-tny7p-vjkoe-i4krp-3qmcl-uqfgr-cpgej-yqtjq-rqe. This exposes users to potential loss of funds on ledgers and unauthorized access to canisters they control.

Solution

Using version >1.0.1 of @dfinity/auth-client and @dfinity/identity packages, or @nfid/embed >0.10.1-alpha.6 includes patched versions of the issue.

User sessions will be automatically fixed when they re-authenticate.

Why this happened

The DFINITY auth client library provides a function, Ed25519KeyIdentity.generate, for generating an Ed25519 key pair. This function includes an optional parameter to supply a 32-byte seed value, which will be utilized as the secret key. In cases where no seed value is provided, the library is expected to generate the secret key using secure randomness. However, a recent update of DFINITY libraries has compromised this assurance by employing an insecure seed for key pair generation.

Details

The Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.6.9.5 via the hash() function due to use of a hardcoded fall-back salt. This makes it possible for unauthenticated attackers to generate a valid token across sites running the plugin that have not manually set a salt in the wp-config.php file and access booking information that will allow them to make modifications.

The access tokens for the REST API are directly derived (sha256 and base64 encoding) from the publicly available default credentials from the Control Dashboard (refer to CVE-2020-10270 for related flaws). This flaw in combination with CVE-2020-10273 allows any attacker connected to the robot networks (wired or wireless) to exfiltrate all stored data (e.g. indoor mapping images) and associated metadata from the robot's database.

GHSA-89RJ-JP6W-RCX3

Vulnerability from github – Published: 2025-05-31 09:30 – Updated: 2025-05-31 09:30
VLAI
Details

The PSW Front-end Login & Registration plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.12 via the customer_registration() function. This is due to the use of a weak, low-entropy OTP mechanism in the forget() function. This makes it possible for unauthenticated attackers to initiate a password reset for any user, including administrators, and elevate their privileges for full site takeover.

GHSA-8C69-R38J-RPFJ

Vulnerability from github – Published: 2023-01-25 19:31 – Updated: 2023-02-07 15:48
VLAI
Summary
Rancher cattle-token is predictable
Details

Impact

An issue was discovered in Rancher versions up to and including 2.6.9 and 2.7.0, where the cattle-token secret, used by the cattle-cluster-agent, is predictable. Even after the token is regenerated, it will have the same value. This issue is not present in Rancher 2.5 releases.

The cattle-token is used by Rancher's cattle-cluster-agent to connect to the Kubernetes API of Rancher provisioned downstream clusters. The problem occurs because the cattle-token secret does not use any random value in its composition, which causes it to always be regenerated with the same value. This can pose a serious problem if the token is compromised and needs to be recreated for security purposes.

The usage of the cattle-token by an unauthorized user allows to escalate privileges to the cluster owner of the affected downstream cluster. It does not allow access to Rancher's own local cluster (the cluster where Rancher is provisioned).

Workarounds

In case it is not possible to promptly update to a patched version, a workaround is to use the rotate script provided in the public security advisory CVE-2021-36782 / GHSA-g7j7-h4q8-8w2f, which facilitates the rotation and creation of a new unique downstream cluster token.

Patches

Patched versions include releases 2.6.10, 2.7.1 and later versions.

After upgrading to one of the patched versions, it is highly recommended to rotate the cattle-token in downstream clusters to guarantee that a new random token will be safely regenerated.

The procedure below can rotate the cattle-token and should be executed in each downstream cluster provisioned by Rancher. It is recommended to first test this process in an appropriate development/testing environment.

# Verify the current secret before rotating it
$ kubectl describe secrets cattle-token -n cattle-system

# Delete the secret
$ kubectl delete secrets cattle-token -n cattle-system

# Restart the cattle-cluster-agent deployment
$ kubectl rollout restart deployment/cattle-cluster-agent -n cattle-system

# Confirm that a new and different secret was generated
$ kubectl describe secrets cattle-token -n cattle-system

Mitigation
Architecture and Design
  • Use a well-vetted algorithm that is currently considered to be strong by experts in the field, and select well-tested implementations with adequate length seeds.
  • In general, if a pseudo-random number generator is not advertised as being cryptographically secure, then it is probably a statistical PRNG and should not be used in security-sensitive contexts.
  • Pseudo-random number generators can produce predictable numbers if the generator is known and the seed can be guessed. A 256-bit seed is a good starting point for producing a "random enough" number.
Mitigation
Implementation

Consider a PRNG that re-seeds itself as needed from high quality pseudo-random output sources, such as hardware devices.

Mitigation MIT-2
Architecture and Design Requirements

Strategy: Libraries or Frameworks

Use products or modules that conform to FIPS 140-2 [REF-267] to avoid obvious entropy problems. Consult FIPS 140-2 Annex C ("Approved Random Number Generators").

CAPEC-112: Brute Force

In this attack, some asset (information, functionality, identity, etc.) is protected by a finite secret value. The attacker attempts to gain access to this asset by using trial-and-error to exhaustively explore all the possible secret values in the hope of finding the secret (or a value that is functionally equivalent) that will unlock the asset.

CAPEC-485: Signature Spoofing by Key Recreation

An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

CAPEC-59: Session Credential Falsification through Prediction

This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
