Extreme XDS: Insertion of Sensitive Information Into Sent Data

CVE-2024-7872 is a high-severity insertion of sensitive information into sent data vulnerability in Extreme XDS from ExtremePacs, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists version 3933 as the first without the flaw, so updating Extreme XDS to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Insertion of Sensitive Information Into Sent Data vulnerability in ExtremePACS Extreme XDS allows Retrieve Embedded Sensitive Data. This issue affects Extreme XDS: before 3933.

The underlying weakness: Insertion of Sensitive Information Into Sent Data

The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.

How developers prevent this class of flaw

  • Specify which data in the software should be regarded as sensitive. Consider which types of users should have access to which types of data.
  • Ensure that any possibly sensitive data specified in the requirements is verified with designers to ensure that it is either a calculated risk or mitigated elsewhere. Any information that is not necessary to the functionality should be removed in order to lower both the overhead and the possibility of security sensitive data being sent.
  • Setup default error messages so that unexpected errors do not disclose sensitive information.
