Bugs in the Zimbra Server Could Lead to Unrestricted Email Access


Multiple security flaws have been uncovered in the Zimbra email collaboration software, which could be abused to compromise email accounts by sending a malicious message or even take control of the mail server if it is housed on a cloud infrastructure. Researchers from code quality and security solutions company SonarSource found and reported the flaws in Zimbra 8.8.15 in May 2021, dubbed CVE-2021-35208 and CVE-2021-35209. Since then, Zimbra versions 8.8.15 Patch 23 and 9.0.0 Patch 16 have been released with mitigations. 

"A combination of these vulnerabilities could enable an unauthenticated attacker to compromise a complete Zimbra webmail server of a targeted organization," said SonarSource vulnerability researcher, Simon Scannell, who identified the security weaknesses. "As a result, an attacker would gain unrestricted access to all sent and received emails of all employees." 

Zimbra is a cloud-based email, calendar, and collaboration suite for businesses that comes in both an open-source and commercially supported version with extra capabilities like a proprietary connector API for synchronising mail, calendar, and contacts with Microsoft Outlook, among other things. It's utilised by more than 200,000 companies in 160 countries. 

The first flaw, discovered by Simon Scannell, could be exploited simply by opening a malicious email with a JavaScript payload. A cross-site scripting (XSS) bug (CVE-2021-35208) would be triggered in a victim's browser if they opened such a rigged email. According to SonarSource, when the payload is performed, it gives an attacker access to the victim's emails as well as their webmail session. They also claimed that it would serve as a starting point for additional assaults: “With this, other features of Zimbra could be accessed and further attacks could be launched.”

The second bug is an allow-list bypass that leads to a powerful server-side request forgery (SSRF) vulnerability (CVE-2021-35209) that may be exploited by an authenticated account belonging to a member of a targeted organisation with any permitted role. If the two bugs are combined, a remote attacker will be able to obtain valuable information from cloud infrastructure instances, such as Google Cloud API Tokens or AWS IAM credentials. 

"Zimbra would like to alert its customers that it is possible for them to introduce an SSRF security vulnerability in the Proxy Servlet," the company noted in its advisory. "If this servlet is configured to allow a particular domain (via zimbraProxyAllowedDomains configuration setting), and that domain resolves to an internal IP address (such as, an attacker could possibly access services running on a different port on the same server, which would normally not be exposed publicly."

PayPal Suffered Cross-Site Scripting -XSS Vulnerability


The PayPal currency converter functionality was damaged by severe cross-site scripting (XSS) vulnerability. An attacker might be able to run destructive scripts if the vulnerability is abused. This could lead to the malicious user injecting malicious JavaScript, HTML, or some other form of browser file. The bug was noticed on PayPal's web domain with the currency converter functionality of PayPal wallets. 

On February 19, 2020, the vulnerability was first identified as a concern of "reflected XSS and CSP bypass" by a security researcher who goes by the name "Cr33pb0y" – he's been granted $2,900 in bug bounty programming by HackerOne. 

PayPal said that a flaw occurred in the currency conversion endpoint which was triggered by an inability to adequately sanitize user feedback, in a restricted disclosure that was released on February 10 – almost a year after the researcher identified the problem privately. 

PayPal acknowledged the flaw- in response to the HackerOne forum, that contributed to the currency translation URL managing user feedback inappropriately. A vulnerability intruder may use the JavaScript injection to access a document object in a browser or apply other malicious code to the URL. If hackers load a malicious payload into the browser of a victim, they can steal data or use the computer to take control of the system. As a consequence, malicious payloads can trigger a victim's browser page without its knowledge or consent in the Document Object Model (DOM). 

Typically, XSS attacks represent a browser's script from a specific website and can enable a target to click a malicious connection. Payloads can be used as a theft point in larger attacks or for the stealing of cookies, session tokens, or account information. PayPal has now carried out further validation tests to monitor users’ feedback in the currency exchange function and wipe out errors following the disclosure of the bug bounty hunter. 

XSS bugs are a frequent hacker attack vector. Several recent leaks of data have been related to bugs like what some analysts claim is an XSS flaw. 

While telling that the vulnerability has been fixed, PayPal said, “by implementing additional controls to validate and sanitize user input before being returned in the response.”

Uploader.swf flash file in vBulletin forum vulnerable to XSS

Attention! vBulletin forums users, there is a flash file in the vBulletin forum software which is vulnerable to Cross site scripting(XSS).

The file "Uploader.swf" is located either in located in 'clientscript/yui/uploader/assets' or '/core/clientscript/yui/uploader/assets'.

"It has come to our attention that there is a security issue in the uploader.swf file included as part of the Yahoo User Interface (YUI) library included in vBulletin 4. As the version of YUI included in vBulletin is end-of-lifed, Yahoo will not be fixing this issue." vBulletin Security advisory reads.

vBulletin recommends users to delete the Uploader.swf file from your forums and replace it with another empty file provided in their forum.  This will force the vBulletin to use javascript based uploader instead.

Proof of concept:

Critical security vulnerabilities patched in Adobe Flash Player and ColdFusion

Adobe has issued security hotfix for two critical vulnerabilities in ColdFusion web application server.  They have also issued security update for the Adobe Flash player.

The cross site scripting(XSS) vulnerability (CVE-2013-5326) could be exploited by a remote, authenticated user on ColdFusion 10 and earlier versions when the CFIDE directory is exposed. 

The other vulnerability in ColdFusion is "unauthorized remote access(CVE-2013-5328)"- marked as critical security flaw.

Adobe Flash Player 11.9.900.117 and earlier versions are vulnerable to a critical bug that "could cause a crash and potentially allow an attacker to take control of the affected system".

OpenEMR affected by Multiple Vulnerabilities

The most popular open source electronic medical records (OpenEMR) is said to have multiple vulnerabilities by the Trustwave SpiderLabs.

It reported that with a guest access, mixed with some application issues the user was able to compromise with the server running OpenEMR and it even served as a dock for attacking the internal networks.

The Researcher found a SQL Injection vulnerability in "Reports > Visits > SuperBill > Dates" location. 

"By browsing to this page and dumping in junk in either the start or end date parameters", he saw the SQL error message saying "ERROR: query failed: select * from forms where form_name = 'New Patient Encounter' and date between 'a'' and '2013-07-12' order by date DESC"

It also claimed to dump most of the database contents and important datas of patients as well as numerous usernames and passwords." I let my GPU box chew on the password hashes for a bit, and kept poking at the application." (the blog says)

OpenEMR is also reported to have HTML injection/XSS on an 'Office Notes' page. The user was even able to beguile the user visiting the page to attempt authentication with his system, which was hosting a fake SMB server with static challenges:

"This allowed me to capture a handful of domain usernames and password hashes. In addition, I had some luck cracking the OpenEMR password hashes from earlier, and some of the passwords were re-used locally on the Linux system hosting OpenEMR, allowing me access via SSH."(SpiderLabs reports)

The OpenEMR has been informed of it and they have patched the vulnerabilities in the latest 4.1.1 patch.
