Latest Critical Atlassian Confluence Vulnerability Under Active Exploitation

A week after Atlassian rolled out patches to contain a critical flaw in its Questions For Confluence app for Confluence Server and Confluence Data Center, the shortcoming has now come under active exploitation in the wild.
The bug in question is CVE-2022-26138, which concerns the use of a hard-coded password in the app that could be exploited by a remote, unauthenticated attacker to gain unrestricted access to all pages in Confluence.
The real-world exploitation follows the release of the hard-coded credentials on Twitter, prompting the Australian software company to prioritize patches to mitigate potential threats targeting the flaw.
“Unsurprisingly, it didn’t take long […] to observe exploitation once the hard-coded credentials were released, given the high value of Confluence for attackers who often jump on Confluence vulnerabilities to execute ransomware attacks,” Rapid7 security researcher Glenn Thorpe said.
It’s worth noting that the bug only exists when the Questions for Confluence app is enabled. That said, uninstalling the Questions for Confluence app does not remediate the flaw, as the created account does not get automatically removed after the app has been uninstalled.
Users of the affected product are advised to update their on-premise instances to the latest versions (2.7.38 and 3.0.5) as soon as possible, or take steps to disable/delete the account.
The development also arrives as Palo Alto Networks, in its 2022 Unit 42 Incident Response Report, found that threat actors are scanning for vulnerable endpoints within 15 minutes of public disclosure of a new security flaw.

By Jon Munshaw. Welcome to this week’s edition of the Threat Source newsletter. After what seems like forever and honestly has been a really long time, we’re heading back to BlackHat in-person this year. We’re excited to see a lot of old friends again to commiserate, hang out, trade stories and generally talk about security. Throughout the two days of the main conference, we’ll have a full suite of flash talks at the Cisco Secure booth and several sponsored talks. Since this is the last edition of the newsletter before BlackHat starts, it’s probably worthwhile running through all the cool stuff we’ll have going on at Hacker Summer Camp. Our booth should be easy enough to find — it’s right by the main entrance to Bayside B. If you get to the Trellix Lounge, you’ve gone too far north. Our researchers will be there to answer any questions you have and present on a wide variety of security topics, from research into Adobe vulnerabilities to the privacy effects of the overtur...
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added the recently disclosed Atlassian security flaw to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. The vulnerability, tracked as CVE-2022-26138, concerns the use of hard-coded credentials when the Questions For Confluence app is enabled in Confluence Server and Data Center
Attackers almost immediately leapt on a just-disclosed bug, CVE-2022-26138, affecting Atlassian Confluence, which allows remote, unauthenticated actors unfettered access to Confluence data.
A hardcoded password associated with the Questions for Confluence app has been publicly released, which will likely lead to exploit attempts that give cyberattackers access to all Confluence content.
Jira, Bamboo, Bitbucket, Confluence, Fisheye/Crucible, and Questions for Confluence affected
Atlassian has rolled out fixes to remediate a critical security vulnerability pertaining to the use of hard-coded credentials affecting the Questions For Confluence app for Confluence Server and Confluence Data Center. The flaw, tracked as CVE-2022-26138, arises when the app in question is enabled on either of two services, causing it to create a Confluence user account with the username "
The Atlassian Questions For Confluence app for Confluence Server and Data Center creates a Confluence user account in the confluence-users group with the username disabledsystemuser and a hardcoded password. A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence and access all content accessible to users in the confluence-users group. This user account is created when installing versions 2.7.34, 2.7.35, and 3.0.2 of the app.
