Summary
CVE-2024-23945 is a medium-severity Generation of Error Message Containing Sensitive Information (CWE-209) vulnerability in Apache Spark. Its CVSS base score is 5.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 25% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SI-11 (Error Handling) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-23945 affects the cookie signing logic in Apache Hive’s service component (org.apache.hive:hive-service) and the corresponding Spark Hive Thriftserver modules (spark-hive-thriftserver_2.11 and _2.12). The flaw, introduced by HIVE-9710 in Hive 1.2.0 and SPARK-14987 in Spark 2.0.0, causes the correct signed cookie value to be returned to a client whenever a signature mismatch occurs between the supplied and expected cookie, exposing the signature that is otherwise intended to protect integrity.
An unauthenticated remote attacker can trigger the mismatch condition over the network to obtain a valid cookie signature. With the signature in hand, the attacker can forge or modify subsequent cookies, achieving integrity violations that the signing mechanism was designed to prevent. The CVSS 5.9 rating reflects the high attack complexity required to reach this outcome despite the absence of required credentials.
Public references point to corrective commits in the Hive and Spark repositories that address the exposure in the CookieSigner path. The EPSS score reached a peak of 0.0852 after disclosure, indicating a measurable increase in observed exploitation interest from an initially low baseline.

Vulnerability Data
Signing cookies is an application security feature that adds a digital signature to cookie data to verify its authenticity and integrity. The signature helps prevent malicious actors from modifying the cookie value, which can lead to security vulnerabilities and exploitation.…
more
Apache Hive’s service component accidentally exposes the signed cookie to the end user when there is a mismatch in signature between the current and expected cookie. Exposing the correct cookie signature can lead to further exploitation. The vulnerable CookieSigner logic was introduced in Apache Hive by HIVE-9710 (1.2.0) and in Apache Spark by SPARK-14987 (2.0.0). The affected components are the following: * org.apache.hive:hive-service * org.apache.spark:spark-hive-thriftserver_2.11 * org.apache.spark:spark-hive-thriftserver_2.12
