A vulnerability in multiple Atlassian products allows a remote, unauthenticated attacker to bypass Servlet Filters used by first and third party apps. The impact depends on which filters are used by each app, and how the filters are used. This vulnerability can result in authentication bypass and cross-site scripting. Atlassian has released updates that fix the root cause of this vulnerability, but has not exhaustively enumerated all potential consequences of this vulnerability. Atlassian Bamboo versions are affected before 8.0.9, from 8.1.0 before 8.1.8, and from 8.2.0 before 8.2.4. Atlassian Bitbucket versions are affected before 7.6.16, from 7.7.0 before 7.17.8, from 7.18.0 before 7.19.5, from 7.20.0 before 7.20.2, from 7.21.0 before 7.21.2, and versions 8.0.0 and 8.1.0.

A vulnerability in multiple Atlassian products allows a remote, unauthenticated attacker to cause additional Servlet Filters to be invoked when the application processes requests or responses. Atlassian has confirmed and fixed the only known security issue associated with this vulnerability: Cross-origin resource sharing (CORS) bypass. Sending a specially crafted HTTP request can invoke the Servlet Filter used to respond to CORS requests, resulting in a CORS bypass. An attacker that can trick a user into requesting a malicious URL can access the vulnerable application with the victim’s permissions. Atlassian Bamboo versions are affected before 8.0.9, from 8.1.0 before 8.1.8, and from 8.2.0 before 8.2.4. Atlassian Bitbucket versions are affected before 7.6.16, from 7.7.0 before 7.17.8, from 7.18.0 before 7.19.5, from 7.20.0 before 7.20.2, from 7.21.0 before 7.21.2, and versions 8.0.0 and 8.1.0. Atlassian Confluence versions are affected before 7.4.17, from 7.5.0 before 7.13.7, from 7.1…

The /rest-service-fecru/server-v1 resource in Fisheye and Crucible before version 4.8.9 allowed authenticated remote attackers to obtain information about installation directories via information disclosure vulnerability.

Affected versions of Atlassian Fisheye & Crucible allowed remote attackers to browse local files via an Insecure Direct Object References (IDOR) vulnerability in the WEB-INF directory and bypass the fix for CVE-2020-29446 due to a lack of url decoding. The affected versions are before version 4.8.9.

Various rest resources in Fisheye and Crucible before version 4.8.9 allowed remote attackers to brute force user login credentials as rest resources did not check if users were beyond their max failed login limits and therefore required solving a CAPTCHA in addition to providing user credentials for authentication via a improper restriction of excess authentication attempts vulnerability.

The jQuery deserialize library in Fisheye and Crucible before version 4.8.9 allowed remote attackers to to inject arbitrary HTML and/or JavaScript via a prototype pollution vulnerability.

The DefaultRepositoryAdminService class in Fisheye and Crucible before version 4.8.9 allowed remote attackers, who have 'can add repository permission', to enumerate the existence of internal network and filesystem resources via a Server-Side Request Forgery (SSRF) vulnerability.

Affected versions of Atlassian Fisheye & Crucible allow remote attackers to browse local files via an Insecure Direct Object References (IDOR) vulnerability in the WEB-INF directory. The affected versions are before version 4.8.5.
