Two Critical Flaws Found in Alibaba Cloud's PostgreSQL Databases

Two Critical Flaws Found in Alibaba Cloud's PostgreSQL Databases

Apr 20, 2023 Cloud Security / Vulnerability
A chain of two critical flaws has been disclosed in Alibaba Cloud's ApsaraDB RDS for PostgreSQL and AnalyticDB for PostgreSQL that could be exploited to breach tenant isolation protections and access sensitive data belonging to other customers. "The vulnerabilities potentially allowed unauthorized access to Alibaba Cloud customers' PostgreSQL databases and the ability to perform a supply chain attack on both Alibaba database services, leading to an RCE on Alibaba database services," cloud security firm Wiz  said  in a new report shared with The Hacker News. The  issues , dubbed  BrokenSesame , were reported to Alibaba Cloud in December 2022, following mitigations were deployed by the company on April 12, 2023. There is no evidence to suggest that the weaknesses were exploited in the wild. In a nutshell, the vulnerabilities – a privilege escalation flaw in AnalyticDB and a remote code execution bug in ApsaraDB RDS – made it possible to elevate privileges to root w
Kinsing Crypto Malware Hits Kubernetes Clusters via Misconfigured PostgreSQL

Kinsing Crypto Malware Hits Kubernetes Clusters via Misconfigured PostgreSQL

Jan 09, 2023 Kubernetes / Cryptojacking
The threat actors behind the  Kinsing  cryptojacking operation have been spotted exploiting misconfigured and exposed PostgreSQL servers to obtain initial access to Kubernetes environments. A second initial access vector technique entails the use of vulnerable images, Sunders Bruskin, security researcher at Microsoft Defender for Cloud,  said  in a report last week. Kinsing has a  storied history  of targeting  containerized environments , often leveraging misconfigured open Docker daemon API ports as well as abusing newly disclosed exploits to drop cryptocurrency mining software. The threat actor, in the past, has also been discovered  employing a rootkit  to hide its presence, in addition to terminating and uninstalling competing resource-intensive services and processes. Now according to Microsoft, misconfigurations in  PostgreSQL servers  have been co-opted by the Kinsing actor to gain an initial foothold, with the company observing a "large amount of clusters" infe
Midnight Blizzard and Cloudflare-Atlassian Cybersecurity Incidents: What to Know

Midnight Blizzard and Cloudflare-Atlassian Cybersecurity Incidents: What to Know

Feb 13, 2024SaaS Security / Data Breach
The Midnight Blizzard and Cloudflare-Atlassian cybersecurity incidents raised alarms about the vulnerabilities inherent in major SaaS platforms. These incidents illustrate the stakes involved in SaaS breaches — safeguarding the integrity of SaaS apps and their sensitive data is critical but is not easy. Common threat vectors such as sophisticated spear-phishing, misconfigurations and vulnerabilities in third-party app integrations demonstrate the complex security challenges facing IT systems. In the case of Midnight Blizzard, password spraying against a test environment was the initial attack vector. For Cloudflare-Atlassian, threat actors initiated the attack via compromised  OAuth tokens  from a prior breach at Okta, a SaaS identity security provider.  What Exactly Happened? Microsoft Midnight Blizzard Breach Microsoft was targeted by the Russian "Midnight Blizzard" hackers (also known as Nobelium, APT29, or Cozy Bear) who are linked to the SVR, the Kremlin's forei
Researchers Disclose Supply-Chain Flaw Affecting IBM Cloud Databases for PostgreSQL

Researchers Disclose Supply-Chain Flaw Affecting IBM Cloud Databases for PostgreSQL

Dec 02, 2022 Kubernetes / Cloud Security
IBM has fixed a high-severity security vulnerability affecting its Cloud Databases (ICD) for PostgreSQL product that could be potentially exploited to tamper with internal repositories and run unauthorized code. The privilege escalation flaw (CVSS score: 8.8), dubbed " Hell's Keychain " by cloud security firm Wiz, has been described as a "first-of-its-kind supply-chain attack vector impacting a cloud provider's infrastructure." Successful exploitation of the bug could enable a malicious actor to remotely execute code in customers' environments and even read or modify data stored in the PostgreSQL database. "The vulnerability consists of a chain of three exposed secrets (Kubernetes service account token, private container registry password, CI/CD server credentials) coupled with overly permissive network access to internal build servers," Wiz researchers Ronen Shustin and Shir Tamari  said . Hell's Keychain commences with an SQL inject

Microsoft Azure Vulnerability Exposes PostgreSQL Databases to Other Customers

Microsoft Azure Vulnerability Exposes PostgreSQL Databases to Other Customers

Apr 29, 2022
Microsoft on Thursday disclosed that it addressed a pair of issues with the Azure Database for PostgreSQL Flexible Server that could result in unauthorized cross-account database access in a region. "By exploiting an elevated permissions bug in the Flexible Server authentication process for a replication user, a malicious user could leverage an improperly anchored regular expression to bypass authentication to gain access to other customers' databases," Microsoft Security Response Center (MSRC)  said . New York City-based cloud security company Wiz, which uncovered the flaws, dubbed the exploit chain " ExtraReplica ." Microsoft said it mitigated the bug within 48 hours of disclosure on January 13, 2022. Specifically, it relates to a case of privilege escalation in the Azure PostgreSQL engine to gain code execution and a cross-account authentication bypass by means of a forged certificate, allowing an attacker to create a database in the target's Azure r
