EMC Elastic Cloud Storage (ECS) before 3.1 is affected by an undocumented account vulnerability that could potentially be leveraged by malicious users to compromise the affected system.

Dell EMC ECS versions 3.2.0.0 and 3.2.0.1 contain an authentication bypass vulnerability. A remote unauthenticated attacker could exploit this vulnerability to read and modify S3 objects by supplying specially crafted S3 requests.

Dell EMC ECS versions prior to 3.4.0.0 contain an improper restriction of excessive authentication attempts vulnerability. An unauthenticated remote attacker may potentially perform a password brute-force attack to gain access to the targeted accounts.

Dell ECS, versions prior to 3.8.1.3 contains an arithmetic overflow vulnerability exists in retention period handling of ECS. An authenticated user with bucket or object-level access and the necessary privileges could potentially exploit this vulnerability to bypass retention policies and delete objects.

Dell EMC ECS, versions prior to 3.5, contains an Exposure of Resource vulnerability. A remote unauthenticated attacker can access the list of DT (Directory Table) objects of all internally running services and gain knowledge of sensitive data of the system.

DELL ECS prior to 3.8.0.2 contains an improper verification of cryptographic signature vulnerability. A network attacker with an ability to intercept the request could potentially exploit this vulnerability to modify the body data of the request.

Dell ECS, versions 3.6 through 3.6.2.5, and 3.7 through 3.7.0.6, and 3.8 through 3.8.0.4 versions, contain an improper access control vulnerability. A remote high privileged attacker could potentially exploit this vulnerability, leading to unauthorized access to all buckets and their data within a namespace

Dell ECS, versions prior to 3.8.1, contain a privilege elevation vulnerability in user management. A remote high privileged attacker could potentially exploit this vulnerability, gaining access to unauthorized end points.

Dell ECS version 3.8.1.4 and prior contain an Improper Certificate Validation vulnerability. An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Information disclosure.

Dell ECS, version(s) prior to ECS 3.8.1.3, contain(s) an Authentication Bypass by Capture-replay vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Session theft.

Dell EMC ECS versions prior to 3.4.0.1 contain an XSS vulnerability. A remote authenticated malicious user could exploit this vulnerability to store malicious HTML or JavaScript code in a trusted application data store. When victim users access the data store through their browsers, the malicious code gets executed by the web browser in the context of the vulnerable web application.

Dell ECS, versions prior to 3.8.0, contain(s) a Host Header Injection Vulnerability. A remote low-privileged attacker could potentially exploit this vulnerability to trigger redirections that leads to sensitive information leakage.
