Apache Doris: Observable Timing Discrepancy
CVE-2023-41313 is a critical-severity observable timing discrepancy vulnerability in Apache Doris from Apache, 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. The record lists version 1.2.8 as the first without the flaw, so updating Apache Doris to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.06% chance of exploitation within 30 days, higher than 65% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Apache Doris to 1.2.8 or a later version.
- Update doris to 1.2.8 or a later version.
- Read the advisory on lists.apache.org for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Apache | Apache Doris | before 1.2.8 | 1.2.8 |
| Apache | doris | before 1.2.8 | 1.2.8 |

Official description
The authentication method in Apache Doris versions before 2.0.0 was vulnerable to timing attacks. Users are recommended to upgrade to version 2.0.0 + or 1.2.8, which fixes this issue.

The underlying weakness: Observable Timing Discrepancy
Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not.
