The Hacker News reports that Atlassian has issued fixes for critical security vulnerabilities in its Bitbucket Server, Crowd, and Data Center offerings.
Atlassian BitBucket Server and Data Center versions 7.0 to 7.21 and 8.0 to 8.4 with false mesh.enabled are impacted by CVE-2022-43781, a command injection flaw that could help facilitate code execution.
Disabling the "Public Signup" option could curb exploitation of the flaw as a temporary workaround, according to Atlassian.
"ADMIN or SYS_ADMIN authenticated users still have the ability to exploit the vulnerability when public signup is disabled," Atlassian noted.
Meanwhile, Crowd Server and Data Center products are affected by the second bug, CVE-2022-43782, which involves a misconfiguration that could enable invoking of privileged API endpoints as long as attackers are connected from an IP address included in Remote Access configuration. Immediate patching of the aforementioned flaws has been recommended as exploitation of Atlassian and Bitbucket flaws have been prevalent.
Included in the exposed dataset labeled "PDL" were individuals' full names, email addresses, phone numbers, location data, professional summaries, and skills, as well as education and employment histories.
Attackers could leverage the issue — which impacts Nexus 3000, 7000, and 9000 series switches with vulnerable NX-OS versions with DHCPv6 activated and are in standalone NX-OS mode — to facilitate continuous crashes of the dhcp_snoop process and a denial-of-service condition.
Higher rewards of up to $250,000 will be given by Google for the discovery of memory corruption flaws in the Chrome browser shown to achieve remote code execution using a non-sandboxed process as part of a more robust vulnerability reward program.
