iBoot PDU: Deserialization of Untrusted Data

Published Updated By the CyberSecBulletin desk

CVE-2023-3259 is a critical-severity deserialization of untrusted data vulnerability in iBoot PDU from Dataprobe, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected iBoot PDU versions: 1.43.03312023 through <= 1.43.03312023; 1.43.03312023. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.95% chance of exploitation within 30 days, higher than 62% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update Iboot-pdu4a-c10 Firmware to 1.44.0804202 or a later version.
  2. Update Iboot-pdu4a-c20 Firmware to 1.44.0804202 or a later version.
  3. Update Iboot-pdu4a-n15 Firmware to 1.44.0804202 or a later version.
  4. Read the advisory on trellix.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The Dataprobe iBoot PDU running firmware version 1.43.03312023 or earlier is vulnerable to authentication bypass. By manipulating the IP address field in the "iBootPduSiteAuth" cookie, a malicious agent can direct the device to connect to a rouge database.Successful exploitation allows the malicious agent to take actions with administrator privileges including, but not limited to, manipulating power levels, modifying user accounts, and exporting confidential user information

The underlying weakness: Deserialization of Untrusted Data

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

How developers prevent this class of flaw

  • If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
  • When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
  • Explicitly define a final object() to prevent deserialization.
