Incorrect Authorization

An issue was discovered in Xen through 4.11.x. The DEBUGCTL MSR contains several debugging features, some of which virtualise cleanly, but some do not. In particular, Branch Trace Store is not virtualised by the processor, and software has to be careful to configure it suitably not to lock up the core. As a result, it must only be available to fully trusted guests. Unfortunately, in the case that vPMU is disabled, all value checking was skipped, allowing the guest to choose any MSR_DEBUGCTL setting it likes. A malicious or buggy guest administrator (on Intel x86 HVM or PVH) can lock up the entire host, causing a Denial of Service.Show less

It was discovered that PostgreSQL versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 failed to properly check authorization on certain statements involved with "INSERT ... ON CONFLICT DO UPDATE". An attacker with "CREATE TABLE" privileges could exploit this to read arbitrary bytes server memory. If the attacker also had certain "INSERT" and limited "UPDATE" privileges to a particular table, they could exploit this to update other columns in the same table.Show less

NetApp 7-Mode Transition Tool allows users with valid credentials to access functions and information which may have been intended to be restricted to administrators or privileged users. 7MTT versions below 2.0 do not enforce user authorization rules on file information and status that it has previously collected. The released version of 7MTT has been updated to maintain and verify authorization rules for file information, status and utilities.Show less

Huawei smartphones with software Victoria-AL00 8.0.0.336a(C00) have an information leakage vulnerability. Because an interface does not verify authorization correctly, attackers can exploit an application with the authorization of phone state to obtain user location additionally.Show less

A logic error in valid_role() in CloudForms role validation before 5.7.1.3 could allow a tenant administrator to create groups with a higher privilege level than the tenant administrator should have. This would allow an attacker with tenant administration access to elevate privileges.Show less

Cloud Foundry UAA, versions 4.19 prior to 4.19.2 and 4.12 prior to 4.12.4 and 4.10 prior to 4.10.2 and 4.7 prior to 4.7.6 and 4.5 prior to 4.5.7, incorrectly authorizes requests to admin endpoints by accepting a valid refresh token in lieu of an access token. Refresh tokens by design have a longer expiration time than access tokens, allowing the possessor of a refresh token to authenticate longer than expected. This affects the administrative endpoints of the UAA. i.e. /Users, /Groups, etc. However, if the user has been deleted or had groups removed, or the client was deleted, the refresh token will no longer be valid.Show less

Sage XRT Treasury, version 3, fails to properly restrict database access to authorized users, which may enable any authenticated user to gain full access to privileged database functions. Sage XRT Treasury is a business finance management application. Database user access privileges are determined by the USER_CODE field associated with the querying user. By modifying the USER_CODE value to match that of a privileged user, a low-privileged, authenticated user may gain privileged access to the SQL database. A remote, authenticated user can submit specially crafted SQL queries to gain privileged access to the application database.Show less

A Improper authorization vulnerability exists in Jenkins 2.132 and earlier, 2.121.1 and earlier in SlaveComputer.java that allows attackers with Overall/Read permission to initiate agent launches, and abort in-progress agent launches.Show less

An authorization-check flaw was discovered in federation configurations of the OpenStack Identity service (keystone). An authenticated federated user could request permissions to a project and unintentionally be granted all related roles including administrative roles.Show less

RSA Identity Lifecycle and Governance versions 7.0.1, 7.0.2 and 7.1.0 contains an authorization bypass vulnerability within the workflow architect component (ACM). A remote authenticated malicious user with non-admin privileges could potentially bypass the Java Security Policies. Once bypassed, a malicious user could potentially run arbitrary system commands at the OS level with application owner privileges on the affected system.Show less

All ADB broadband gateways / routers based on the Epicentro platform are affected by an authorization bypass vulnerability where attackers are able to access and manipulate settings within the web interface that are forbidden to end users (e.g., by the ISP). An attacker would be able to enable the TELNET server or other settings as well.Show less

An issue was discovered on D-Link DIR-890L with firmware 1.21B02beta01 and earlier, DIR-885L/R with firmware 1.21B03beta01 and earlier, and DIR-895L/R with firmware 1.21B04beta04 and earlier devices (all hardware revisions). Due to the predictability of the /docs/captcha_(number).jpeg URI, being local to the network, but unauthenticated to the administrator's panel, an attacker can disclose the CAPTCHAs used by the access point and can elect to load the CAPTCHA of their choosing, leading to unauthorized login attempts to the access point.Show less
