ZIMBRA DESKTOP ISSUES SOFTWARE
The software alone cannot be expected to defend against the constant onslaught of ever-evolving attack methods.Zimbra desktop is an offline client that lets you manage your various email accounts in one desktop tool. Zimbra has done an exemplary job of expediting the development and release of the patches once the vulnerabilities were discovered, but this situation still serves as a reminder that in addition to software vendors enhancing security related processes in the software development phase, it is also crucial for businesses to remind employees to be wary of suspicious emails and train them to spot malware, and what actions to take when they receive unsolicited attachments. While virtual collaborative office software has evolved to keep up with the increasingly virtualized office environment, these vulnerabilities demonstrate the need for constant vigilance in software supply chain security. There were some issues with previous versions of these patches that have since been repaired.
ZIMBRA DESKTOP ISSUES INSTALL
The XSS attack described above has been fixed by removing the code that transformed the form tag altogether.ĭownload and install the following recommended patches This would also protect against Open Redirect vulnerabilities. It makes sense to validate the value of the Location header of the response and create a new request after it has been validated. SSRF attacks like the one described above can be mitigated by disallowing the HTTP request handler to follow redirects. This is mainly because they enable an attacker to set arbitrary headers in the outgoing request, and also because it allows the attacker to read the response.įor example, if the server is hosted in the Google Cloud Platform, an API access token could be leaked by forging a request to: SSRF vulnerabilities can be extremely damagingĬloud-native applications are at especially high risk from the SSRF vulnerability category. In the event of either of these situations, the attackers would be allowed to install malicious JavaScript code via the Zimbra web client based on Ajax, static HTML and mobile optimization, and then be able to execute the removal of the HTML content in the mail received by the server. According to the researchers, this vulnerability can be used to exploit the server using any authenticated user, regardless of their privileges.

Upon execution of the payload, an attacker will have complete access to all of the victim’s email inbox and outbox (with the exception of their webmail session information), along with full access to other functions of the Zimbra suite, enabling a variety of additional attacks.Ī server-side request forgery vulnerability (CVE-2021-35209) leads to a possible and powerful server-side request forgery by bypassing the allowed list of access control. The email containing the malware will have a sophisticated JavaScript Payload. CVE-2021-35209 (CVSS score: 6.1)- Server-Side Request Forgery (SSRF)Ī cross-site scripting vulnerability (CVE-2021-35208) will be triggered when a user accesses emails from Zimbra.CVE-2021-35208 (CVSS score: 5.4)- DOM-based Stored Cross-Site-Scripting (XSS).As a result, an attacker would gain unrestricted access to all sent and received emails of all employees. A combination of these vulnerabilities could enable an unauthenticated attacker to compromise a targeted organization’s Zimbra webmail server. Two open-source code vulnerabilities recently discovered by security experts at SonarSource may allow attackers to compromise company webmail servers that are using Zimbra. More than 200,000 companies and over 1,000 governments and financial institutions use Zimbra’s messaging service, which works by connecting the information and activities of end users to the private cloud, and every day, millions of people use it to exchange emails.
