IPx: Plaintext Storage of a Password
CVE-2026-63315 is a high-severity plaintext storage of a password vulnerability in IPx from Slican, with a CVSS 4.0 base score of 8.2 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 6.62.0100 as the first without the flaw, so updating IPx to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.29% 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 IPx to 6.62.0100 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Plaintext Storage of a Password
The product stores a password in plaintext within resources such as memory or files.
How developers prevent this class of flaw
- Avoid storing passwords in easily accessible locations.
- Consider storing cryptographic hashes of passwords as an alternative to storing in plaintext.
- A programmer might attempt to remedy the password management problem by obscuring the password with an encoding function, such as base 64 encoding, but this effort does not adequately protect the password because the encoding can be detected and decoded easily.
