CVE-2026-8735 Details
Description
A vulnerability was identified in Oinone Pamirs up to 7.2.0. This affects the function JsonUtils.parseMap of the file PamirsParserConfig.java of the component appConfigQuery Interface. Such manipulation leads to deserialization. The attack can be launched remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
A deserialization vulnerability allowing remote code execution has been identified in Oinone Pamirs versions through 7.2.0. The issue arises in the 'appConfigQuery' interface, which is accessible without authentication. The vulnerability is triggered when the 'JsonUtils.parseMap' function processes a JSON string containing malicious instructions. This manipulation exploits a configuration flaw that disables Fastjson's security features, allowing attackers to execute arbitrary commands on the server.
Remove the 'setAutoTypeSupport(true)' configuration from 'PamirsParserConfig.java' to restore Fastjson's default security settings. If polymorphic deserialization is necessary, restrict allowed classes to safe internal package names. Additionally, upgrade Fastjson to version 2.x or 1.2.83+ and use its 'SafeMode' feature.
