PowerStore 500T: Use of a Broken or Risky Cryptographic Algorithm
CVE-2026-116413 is a high-severity use of a broken or risky cryptographic algorithm vulnerability in PowerStore 500T from Dell, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 5.1.0.0-2798105 or later as the first without the flaw, so updating PowerStore 500T to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.2% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update PowerStore 500T to 5.1.0.0-2798105 or later or a later version.
- Update PowerStore 1000T to 5.1.0.0-2798105 or later or a later version.
- Update PowerStore 1200T to 5.1.0.0-2798105 or later or a later version.

Official description
Dell PowerStore contains a use-of-broken-cryptography vulnerability. A low-privileged attacker could exploit it to impersonate another identity, potentially leading to unauthorized access.

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.
