TencentOS Server 4: storm (TSSA-2026:1032)

medium Nessus Plugin ID 349538

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:1032 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2026-82433:
getNimbusConf returned the complete daemon configuration without redaction after only a user-level authorization check. Where the cluster is configured with them, that response includes storm.zookeeper.auth.payload and the keystore and truststore passwords for the Thrift, Netty and ZooKeeper TLS configuration. The UI endpoint /api/v1/cluster/configuration carried no @AuthNimbusOp annotation, so the authorization filter treated a missing annotation as no gate required and returned immediately, so the endpoint applied no per-user check at all and proxied the request under the UI daemon's own principal.

CVE-2026-68497:
jackson-databind binds a JSON string to a javax.xml.datatype.Duration or XMLGregorianCalendar field by passing the raw string verbatim to DatatypeFactory.newDuration(value) or newXMLGregorianCalendar(value), bypassing jackson's stringified-number length guard and triggering quadratic CPU via BigInteger/BigDecimal parsing; unauthenticated attacker can force minutes of single-threaded CPU work with a few-MB request.
Affects com.fasterxml.jackson.core:jackson-databind 2.0.0 before 2.18.10, 2.19.0 before 2.21.6, 2.22.0 before 2.22.2, and tools.jackson.core 3.0.0 before 3.1.6 / 3.2.0 before 3.2.2.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
