CVE-2021-26084 Confluence Server OGNL injection

Description

In affected versions of Confluence Server and Data Center, an OGNL injection vulnerability exists that would allow an authenticated user, and in some instances an unauthenticated user, to execute arbitrary code on a Confluence Server or Data Center instance. The vulnerable endpoints can be accessed by a non-administrator user or unauthenticated user if ‘Allow people to sign up to create their account’ is enabled. To check whether this is enabled go to COG > User Management > User Signup Options. The affected versions are before version 6.13.23, from version 6.14.0 before 7.4.11, from version 7.5.0 before 7.11.6, and from version 7.12.0 before 7.12.5.

Stating its rating (exploitability & attacker value) without providing additional details is not useful to end users. Please provide more details when creating future assessments as I’ve noticed you’ve provided similar one line assessments for at least 2-3 other vulnerabilities as well.

Technical Analysis

Threat status: Widespread threat
Attacker utility: Remote code execution
Vulnerability class: Injection

Update October 4, 2021: Sophos is sharing details about a ransomware attack utilizing this vulnerability to provide the attacker’s initial access.

Update September 3, 2021: United States Cyber Command tweeted a warning on September 3, 2021 that mass exploitation of Atlassian Confluence CVE-2021-26084 is ongoing and expected to increase. Defenders are once again urged to update on an emergency basis if they have not already done so. CISA has also released a ransomware awareness guide for of holidays and weekends.

On August 25, 2021, Atlassian published details on CVE-2021-26084, a critical remote code execution vulnerability in Confluence Server and Confluence Data Center. The vulnerability arises from an OGNL injection flaw and allows unauthenticated attackers to execute arbitrary code on Confluence Server or Data Center instances. CVE-2021-26084 carries a CVSSv3 base score of 9.8.

Widespread exploitation of CVE-2021-26084 began September 1, 2021 and is ongoing. Many of the initial attacks have installed coin miners on vulnerable targets; we expect, however, that ransomware operators will begin leveraging this vulnerability quickly. Public proof-of-concept (PoC) code is available as of August 31, 2021. Community researchers have reported opportunistic scanning and exploitation of Confluence honeypots. Confluence Server and Data Center customers should update to a fixed version on an emergency basis.

Affected products

version < 6.13.23
6.14.0 ≤ version < 7.4.11
7.5.0 ≤ version < 7.11.5
7.12.0 ≤ version < 7.12.5

For more information, see Atlassian’s advisory and its associated customer ticket.
