PowerFlex Manager (Appliance): URL Redirection to Untrusted Site
CVE-2025-26483 is a high-severity URL redirection to untrusted site vulnerability in PowerFlex Manager (Appliance) from Dell, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists versions IC 48.378.00, IC 48.383.00 as the first without the flaw, so updating PowerFlex Manager (Appliance) to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.17% 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 PowerFlex Manager (Appliance) to IC 48.378.00 or IC 48.383.00, whichever matches your release line, or a later version.
- Update PowerFlex Manager (Rack) to 3.7.8.0 or 3.8.3.0, whichever matches your release line, or a later version.
- Update Powerflex Appliance Intelligent Catalog to 48.383.00 or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
Dell PowerFlex Manager, versions 4.6.2 and prior, contains an Open Redirect Vulnerability. An unauthenticated attacker could potentially exploit this vulnerability, leading to a targeted application user being redirected to arbitrary web URLs. The vulnerability could be leveraged by attackers to conduct phishing attacks that cause users to divulge sensitive information.

The underlying weakness: URL Redirection to Untrusted Site
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
How developers prevent this class of flaw
- Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs. For example, ID 1 could map to /login.asp and ID 2 could map to http://www.example.com/. Features such as the ESAPI AccessReferenceMap provide this capability.
- Ensure that no externally-supplied requests are honored by requiring that all redirect requests include a unique nonce generated by the application. Be sure that the nonce is not predictable (CWE-330).
