Information Disclosure can occur in sshProfiles.jsd in Hitek Software's Automize because of the Read attribute being set for Users. This allows an attacker to recover encrypted passwords for SSH/SFTP profiles. Verified in all 10.x versions up to and including 10.25, and all 11.x versions up to and including 11.14.

Apache Answer: Predictable Authorization Token Using UUIDv1
Details

Inadequate Encryption Strength vulnerability in Apache Answer.

This issue affects Apache Answer: through 1.4.0.

The ids generated using the UUID v1 version are to some extent not secure enough. It can cause the generated token to be predictable. Users are recommended to upgrade to version 1.4.1, which fixes the issue.

A vulnerability exists in Algo Edge up to 2.1.1 - a previously used (legacy) component of navify® Algorithm Suite. The vulnerability impacts the authentication mechanism of this component and could allow an attacker with adjacent access to the laboratory network and the Algo Edge system to craft valid authentication tokens and access the component.

Vulnerability from github – Published: 2026-03-20 21:55 – Updated: 2026-03-25 14:32
VLAI
Summary
AVideo has an unauthenticated decrypt oracle leaking any ciphertext
Details

Summary

The API plugin exposes a decryptString action without any authentication. Anyone can submit ciphertext and receive plaintext. Ciphertext is issued publicly (e.g., view/url2Embed.json.php), so any user can recover protected tokens/metadata. Severity: High.

Details

  • Entry: plugin/API/get.json.php is unauthenticated.
  • Handler: plugin/API/API.php get_api_decryptString() (lines ~5945–5966): php $string = decryptString($_REQUEST['string']); return new ApiObject($string, empty($string)); No APISecret or user check occurs before decrypting.
  • Public ciphertext source: view/url2Embed.json.php returns playLink/playEmbedLink (encryptString(json_encode(...))) to any caller.

PoC

  1. Obtain ciphertext: GET /view/url2Embed.json.php?url=https://example.com/video.mp4 Copy playLink.
  2. Decrypt without auth: ``` POST /plugin/API/get.json.php?APIName=decryptString Content-Type: application/x-www-form-urlencoded

string= ``` Response contains the plaintext JSON (videoLink, title, users_id, etc.).

Impact

  • Any encrypted payload produced by the platform can be decrypted by anyone.
  • Leaks tokens/links intended to be confidential; enables replay and tampering where secrecy was assumed.

Mitigation

  • Require API secret or authenticated/authorized user for decryptString, or remove the endpoint.
  • Prefer one-way signatures (HMAC) instead of exposing generic decryption.
  • Rotate encryption keys/salts after patch to invalidate exposed ciphertexts.

Mitigation
Architecture and Design

Use an encryption scheme that is currently considered to be strong by experts in the field.

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-192: Protocol Analysis

An adversary engages in activities to decipher and/or decode protocol information for a network or application communication protocol used for transmitting information between interconnected nodes or systems on a packet-switched data network. While this type of analysis involves the analysis of a networking protocol inherently, it does not require the presence of an actual or physical network.

CAPEC-20: Encryption Brute Forcing

An attacker, armed with the cipher text and the encryption algorithm used, performs an exhaustive (brute force) search on the key space to determine the key that decrypts the cipher text to obtain the plaintext.
