Pipeline Integrity Monitor: Use of a Broken or Risky Cryptographic Algorithm

Published Updated By the CyberSecBulletin desk

CVE-2026-81822 is a high-severity use of a broken or risky cryptographic algorithm vulnerability in Pipeline Integrity Monitor from AVEVA, with a CVSS 3.1 base score of 8.4 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected Pipeline Integrity Monitor versions: Versions 2025 SP1 P1 (build 7.1.9580.8513) and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.11% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

The vulnerability, if exploited, could allow a miscreant with read access to PIMBoards project files to reverse engineer PIMBoards users’ app-native passwords through computational brute-forcing of weak hashes, potentially allowing elevation to a PIMBoards administrator user.

The underlying weakness: Use of a Broken or Risky Cryptographic Algorithm

The product uses a broken or risky cryptographic algorithm or protocol.

How developers prevent this class of flaw

  • Ensure that the design allows one cryptographic algorithm to be replaced with another in the next generation or version. Where possible, use wrappers to make the interfaces uniform. This will make it easier to upgrade to stronger algorithms. With hardware, design the product at the Intellectual Property (IP) level so that one cryptographic algorithm can be replaced with another in the next generation of the hardware product.
  • Carefully manage and protect cryptographic keys (see CWE-320). If the keys can be guessed or stolen, then the strength of the cryptography itself is irrelevant.
  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Industry-standard implementations will save development time and may be more likely to avoid errors that can occur during implementation of cryptographic algorithms. Consider the ESAPI Encryption feature.
