Java vulnerability analysis and mitigation
Overview
The NumberUtil.toBigDecimal method in hutool-core v5.8.23 was discovered to contain a stack overflow vulnerability. The vulnerability was disclosed on December 13, 2023, affecting the hutool-core library, a widely-used Java utility library (Hutool Issue).
Technical details
The vulnerability occurs when the NumberUtil.toBigDecimal method is called with the input string "NaN". This triggers an infinite recursion leading to a stack overflow error. The issue manifests in the parseNumber method at NumberUtil.java:2686, which continuously calls itself through toBigDecimal method, eventually causing a StackOverflowError (Hutool Issue). The vulnerability has been assigned a CVSS v3.1 base score of 7.5 HIGH with vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H (NVD).
Impact
When exploited, this vulnerability can cause a denial of service condition through application crashes due to stack overflow. The impact primarily affects the availability of systems using the vulnerable version of hutool-core, as the application will crash when processing certain input values (NVD).
