Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the The Apache Software Foundation breach identified under incident ID THE1764583470.

The analysis begins with a detailed overview of The Apache Software Foundation's information like the linkedin page: https://www.linkedin.com/company/the-apache-software-foundation, the number of followers: 79547, the industry type: Software Development and the number of employees: 2368 employees

After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 604 and after the incident was 600 with a difference of -4 which is could be a good indicator of the severity and impact of the incident.

In the next step of the video, we will analyze in more details the incident and the impact it had on The Apache Software Foundation and their customers.

Organizations using Apache bRPC recently reported "Critical Stack Overflow Vulnerability in Apache bRPC (CVE-2025-59789)", a noteworthy cybersecurity incident.

A critical security vulnerability (CVE-2025-59789, CVSS 9.8) has been discovered in the Apache bRPC framework, allowing remote attackers to crash servers by sending specially crafted JSON data with deeply nested recursive structures.

The disruption is felt across the environment, affecting Apache bRPC servers < 1.15.0 handling HTTP+JSON requests.

In response, moved swiftly to contain the threat with measures like Isolate affected bRPC servers from untrusted networks and Disable HTTP+JSON request handling temporarily, and began remediation that includes Upgrade to Apache bRPC version 1.15.0 (recommended fix) and Apply official patch from GitHub (alternative for unable-to-upgrade systems).

The case underscores how Vulnerability disclosed; patches/upgrades available, and recommending next steps like Upgrade to Apache bRPC 1.15.0 immediately to mitigate the vulnerability, Avoid using `JsonToProtoMessage` with untrusted JSON inputs if upgrade/patch is not feasible and Monitor bRPC servers for unusual JSON payloads or recursive structures.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

MITRE ATT&CK® Correlation Analysis

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with high confidence (95%), with evidence including attack Vector such as Network, remote attackers to crash servers by sending specially crafted JSON data, and entry point such as Network (HTTP+JSON requests to bRPC servers). Under the Impact tactic, the analysis identified Endpoint Denial of Service: Application Exhaustion Flood (T1499.004) with high confidence (100%), with evidence including stack overflow... causing the server to crash, leading to a denial-of-service condition, uncontrolled Recursion / Stack Overflow in json2pb component, and downtime such as Potential server crashes leading to service unavailability and Network Denial of Service: Exploitation of Vulnerabilities (T1498.002) with high confidence (100%), with evidence including cVE-2025-59789... allowing remote attackers to crash servers by sending specially crafted JSON, and attack Vector such as Network, CVSS 9.8 (Critical). Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information: HTML Smuggling (T1027.006) with moderate to high confidence (70%), with evidence including sending specially crafted JSON data with deeply nested recursive structures, and malformed JSON requests (implied obfuscation via structure). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
