Android: Deserialization of Untrusted Data

CVE-2024-10382 is a high-severity deserialization of untrusted data vulnerability in Android from Google, with a CVSS 4.0 base score of 7.3 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 1.7.0-beta02 as the first without the flaw, so updating Android to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.16% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Android to 1.7.0-beta02 or a later version.
  2. 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

There exists a code execution vulnerability in the Car App Android Jetpack Library. CarAppService uses deserialization logic that allows construction of arbitrary java classes. This can lead to arbitrary code execution when combined with specific Java deserialization gadgets. An attacker needs to install a malicious application on victims device to be able to attack any application that uses vulnerable library. We recommend upgrading the library past version 1.7.0-beta02.

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.
