Wing Security recently announced that basic third-party risk assessment is  now available as a free product . But it raises the questions of how SaaS is connected to third-party risk management (TPRM) and what companies should do to ensure a proper SaaS-TPRM process is in place. In this article we will share 5 tips to manage the third-party risks associated with SaaS, but first...  What exactly is Third-Party Risk Management in SaaS? SaaS is rapidly growing, offering businesses convenience, swift implementations, and valuable opportunities. However, this growth introduces a security challenge where risks arise from the interconnected nature of SaaS supply chains. It is clear that before onboarding a new contractor or vendor, we need due diligence, security checks, and referrals. However, we now understand that in the SaaS domain, applications are, in fact, the go-to vendor of choice.  Let's explain: Any employee can very easily connect SaaS vendors to company data, granting them pe

Atlassian has released fixes to contain an actively exploited critical zero-day flaw impacting publicly accessible Confluence Data Center and Server instances. The vulnerability, tracked as  CVE-2023-22515 , is remotely exploitable and allows external attackers to create unauthorized Confluence administrator accounts and access Confluence servers. It does not impact Confluence versions prior to 8.0.0. Confluence sites accessed via an atlassian.net domain are also not vulnerable to this issue. The enterprise software services provider  said  it was made aware of the issue by "a handful of customers." It has been addressed in the following versions of Confluence Data Center and Server - 8.3.3 or later 8.4.3 or later, and 8.5.2 (Long Term Support release) or later The company, however, did not disclose any further specifics about the nature and scale of the exploitation, or the root cause of the vulnerability. Customers who are unable to apply the updates are advised

Atlassian and the Internet Systems Consortium (ISC) have disclosed several security flaws impacting their products that could be exploited to achieve denial-of-service (DoS) and remote code execution. The Australian software services provider  said  that the four high-severity flaws were fixed in new versions shipped last month. This includes - CVE-2022-25647  (CVSS score: 7.5) - A deserialization flaw in the Google Gson package impacting Patch Management in Jira Service Management Data Center and Server CVE-2023-22512  (CVSS score: 7.5) - A DoS flaw in Confluence Data Center and Server CVE-2023-22513  (CVSS score: 8.5) - A RCE flaw in Bitbucket Data Center and Server CVE-2023-28709  (CVSS score: 7.5) - A DoS flaw in Apache Tomcat server impacting Bamboo Data Center and Server The flaws have been addressed in the following versions - Jira Service Management Server and Data Center (versions 4.20.25, 5.4.9, 5.9.2, 5.10.1, 5.11.0, or later) Confluence Server and Data Center (v

Atlassian has  released  updates to address three security flaws impacting its Confluence Server, Data Center, and Bamboo Data Center products that, if successfully exploited, could result in remote code execution on susceptible systems. The list of the flaws is below - CVE-2023-22505  (CVSS score: 8.0) - RCE (Remote Code Execution) in Confluence Data Center and Server (Fixed in versions 8.3.2 and 8.4.0) CVE-2023-22508  (CVSS score: 8.5) - RCE (Remote Code Execution) in Confluence Data Center and Server (Fixed in versions 7.19.8 and 8.2.0) CVE-2023-22506  (CVSS score: 7.5) - Injection, RCE (Remote Code Execution) in Bamboo (Fixed in versions 9.2.3 and 9.3.1) CVE-2023-22505 and CVE-2023-22508 allow an "authenticated attacker to execute arbitrary code which has high impact to confidentiality, high impact to integrity, high impact to availability, and no user interaction," the company said. While the first bug was introduced in version 8.0.0, CVE-2023-22508 was introduc

Atlassian has released fixes to resolve a critical security flaw in Jira Service Management Server and Data Center that could be abused by an attacker to pass off as another user and gain unauthorized access to susceptible instances. The  vulnerability  is tracked as  CVE-2023-22501  (CVSS score: 9.4) and has been described as a case of broken authentication with low attack complexity. "An authentication vulnerability was discovered in Jira Service Management Server and Data Center which allows an attacker to impersonate another user and gain access to a Jira Service Management instance under certain circumstances," Atlassian  said . "With write access to a User Directory and outgoing email enabled on a Jira Service Management instance, an attacker could gain access to signup tokens sent to users with accounts that have never been logged into." The tokens, Atlassian noted, can be obtained in either of the two scenarios - If the attacker is included on Jira i

Australian software company Atlassian has rolled out security updates to address  two critical flaws  affecting Bitbucket Server, Data Center, and Crowd products. The issues, tracked as  CVE-2022-43781  and  CVE-2022-43782 , are both rated 9 out of 10 on the CVSS vulnerability scoring system. CVE-2022-43781, which Atlassian said was introduced in version 7.0.0 of Bitbucket Server and Data Center, affects versions 7.0 to 7.21 and 8.0 to 8.4 (only if mesh.enabled is set to false in bitbucket.properties). The weakness has been described as a case of command injection using environment variables in the software, which could allow an adversary with permission to control their username to gain code execution on the affected system. As a temporary workaround, the company is recommending users turn off the "Public Signup" option (Administration > Authentication). "Disabling public signup would change the attack vector from an unauthenticated attack to an authenticated

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday  added  a recently disclosed critical flaw impacting Atlassian's Bitbucket Server and Data Center to the Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. Tracked as  CVE-2022-36804 , the issue relates to a command injection vulnerability that could allow malicious actors to gain arbitrary code execution on susceptible installations by sending a specially crafted HTTP request. Successful exploitation, however, banks on the prerequisite that the attacker already has access to a public repository or possesses read permissions to a private Bitbucket repository. "All versions of Bitbucket Server and Datacenter released after 6.10.17 including 7.0.0 and newer are affected, this means that all instances that are running any versions between 7.0.0 and 8.3.0 inclusive are affected by this vulnerability," Atlassian  noted  in a late August 2022 advisory. CISA did

Cybersecurity researchers on Wednesday disclosed critical flaws in the Atlassian project and software development platform that could be exploited to take over an account and control some of the apps connected through its single sign-on ( SSO ) capability. "With just one click, an attacker could have used the flaws to get access to Atlassian's publish Jira system and get sensitive information, such as security issues on Atlassian cloud, Bitbucket and on premise products," Check Point Research said in an analysis shared with The Hacker News. After the issues were reported to Atlassian on Jan. 8, 2021, the Australian company deployed a fix as part of its  updates  rolled out on  May 18 . The sub-domains affected by the flaws include -  jira.atlassian.com confluence.atlassian.com getsupport.atlassian.com partners.atlassian.com developer.atlassian.com support.atlassian.com training.atlassian.com Successful exploitation of these flaws could result in a supply-ch
