Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mandates validation and sanitization of user-supplied inputs to prevent XPath injection by ensuring improper neutralization does not occur.
Requires timely remediation of flaws like CVE-2026-24343 through patching to version 1.8.0, eliminating the XPath injection vulnerability.
Enables vulnerability scanning to identify XPath injection issues in Apache HertzBeat and prioritizes their risk-based remediation.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
XPath injection in web-based monitoring app directly enables exploitation of the application over the network to achieve data access/manipulation or RCE.
NVD Description
Improper Neutralization of Data within XPath Expressions ('XPath Injection') vulnerability in Apache HertzBeat. This issue affects Apache HertzBeat: from 1.7.1 before 1.8.0. Users are recommended to upgrade to version 1.8.0, which fixes the issue.
Deeper analysisAI
CVE-2026-24343 is an Improper Neutralization of Data within XPath Expressions, known as XPath Injection (CWE-643), affecting Apache HertzBeat monitoring software. The vulnerability impacts versions from 1.7.1 up to but not including 1.8.0, where user-supplied input is insufficiently sanitized before being processed in XPath queries, allowing malicious payloads to alter query logic.
Attackers with low-privilege authenticated access (PR:L) can exploit this over the network (AV:N) with low complexity (AC:L) and no user interaction (UI:N), achieving high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) without changing scope (S:U). This CVSS 3.1 score of 8.8 indicates potential for remote code execution or data manipulation, such as extracting sensitive configuration data or modifying monitoring alerts.
Apache advisories recommend upgrading to version 1.8.0, which resolves the issue through improved input validation. Details are available in the official Apache announcement at https://lists.apache.org/thread/b2k3jqwffrbo2sy6bl4n0f68kp8bfo1n and the OSS-Security mailing list at http://www.openwall.com/lists/oss-security/2026/02/09/4.
