BIG-IP Next SPK: Insufficiently Protected Credentials

CVE-2024-23306 is a high-severity insufficiently protected credentials vulnerability in BIG-IP Next SPK from F5, with a CVSS 3.1 base score of 7.1 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. The record lists version 1.5.0 as the first without the flaw, so updating BIG-IP Next SPK to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.15% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

A vulnerability exists in BIG-IP Next CNF and SPK systems that may allow access to undisclosed sensitive files. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Insufficiently Protected Credentials

The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.

How developers prevent this class of flaw

  • Use an appropriate security mechanism to protect the credentials.
  • Make appropriate use of cryptography to protect the credentials.
  • Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
