Description: Atlassian revealed that unidentified hackers gained access to a vast quantity of data from its group chat service HipChat by breaking into a cloud server owned by the business. Although Atlassian did not disclose the identity of the prominent third-party software library that was utilised by its HipChat.com service, the business claims that attackers took advantage of a weakness in the library. The business issued instructions on how to reset passwords to all users whose accounts were connected to HipChat and, as a precaution, invalidated the passwords on those accounts. The organisation claims that although hashed passwords, email addresses, and names were accessible to hackers, no financial information was revealed.
Description: Atlassian reveals a data leak that was brought on by the theft of employee login information that was then utilized to obtain data from a third-party vendor. More than 13,200 entries make up the employee file that was uploaded online, and a brief inspection of the file suggests that it contains data on many current employees, including names, email addresses, work departments, and other details. The threat actors obtained information from a third-party vendor using the employee login credentials they had stolen. The business emphasized that the event had no impact on consumer or network data. The business acknowledged the data breach and disclosed that Envoy, a startup that offers workplace management services to the Australian software giant, was the source of the leaked data.
Description: Atlassian Confluence Data Center and Server versions were affected by a critical vulnerability identified as CVE-2023-22527, enabling threat actors to exploit the flaw for cryptomining campaigns. Due to the template injection vulnerability, remote attackers could execute arbitrary code, leading to unauthorized cryptocurrency mining using the organization's resources. This activity not only utilized the compromised infrastructure for mining but also had the potential to disrupt operations and financials through resource exhaustion and increase in operational costs. Atlassian released patches to address the issue, however, systems not updated remained at risk.
Description: Atlassian warned its customers that multiple threat groups are exploiting a Confluence Server zero-day vulnerability in its servers. Any unauthenticated attackers can target its Confluence Server and Data Center by a critical vulnerability that can be exploited for remote code execution. The company advised its users have been advised to prevent access to their Confluence servers from the internet, or simply disable these instances, as all supported versions of Confluence Server and Data Center are affected. However, Atlassian expects fixes to become available soon.
Description: Atlassian discovered a vulnerability in its Confluence Server which they need to patch to remedy a Critical-rated flaw. Confluence Server Webwork OGNL injection vulnerability could allow an authenticated user, or unauthenticated user, to execute arbitrary code on a Confluence Server or Data Center instance. However, Atlassian's own Confluence Cloud was patched but other hosted Confluence offerings might be vulnerable.

FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. Versions prior to 16.0.96 and 17.0.1 through 17.0.9 have a weak default password. By default, this is a 6 digit numeric value which can be brute forced. (This is the app_password parameter). Depending on local configuration, this password could be the extension, voicemail, user manager, DPMA or EPM phone admin password. This issue is fixed in versions 16.0.96 and 17.0.10.
Neuron is a PHP framework for creating and orchestrating AI Agents. In versions 2.8.11 and below, the MySQLWriteTool executes arbitrary SQL provided by the caller using PDO::prepare() + execute() without semantic restrictions. This is consistent with the name (“write tool”), but in an LLM/agent context it becomes a high-risk capability: prompt injection or indirect prompt manipulation can cause execution of destructive queries such as DROP TABLE, TRUNCATE, DELETE, ALTER, or privilege-related statements (subject to DB permissions). Deployments that expose an agent with MySQLWriteTool enabled to untrusted input and/or run the tool with a DB user that has broad privileges are impacted. This issue is fixed in version 2.8.12.
Neuron is a PHP framework for creating and orchestrating AI Agents. Versions 2.8.11 and below use MySQLSelectTool, which is vulnerable to Read-Only Bypass. MySQLSelectTool is intended to be a read-only SQL tool (e.g., for LLM agent querying, however, validation based on the first keyword (e.g., SELECT) and a forbidden-keyword list does not block file-writing constructs such as INTO OUTFILE / INTO DUMPFILE. As a result, an attacker who can influence the tool input (e.g., via prompt injection through a public agent endpoint) may write arbitrary files to the DB server if the MySQL/MariaDB account has the FILE privilege and server configuration permits writes to a useful location (e.g., a web-accessible directory). This issue is fixed in version 2.8.12.
Okta Java Management SDK facilitates interactions with the Okta management API. In versions 11.0.0 through 20.0.0, race conditions may arise from concurrent requests using the ApiClient class. This could cause a status code or response header from one request’s response to influence another request’s response. This issue is fixed in version 20.0.1.
The Auth0 Next.js SDK is a library for implementing user authentication in Next.js applications. When using versions 4.11.0 through 4.11.2 and 4.12.0, simultaneous requests on the same client may result in improper lookups in the TokenRequestCache for the request results. This issue is fixed in versions 4.11.2 and 4.12.1.
