Incorrect Authorization

A flaw was found in PostgreSQL in versions before 13.2. This flaw allows a user with SELECT privilege on one column to craft a special query that returns all columns of the table. The highest threat from this vulnerability is to confidentiality.Show less

Applications using the “Sensitive Headers” functionality in Spring Cloud Netflix Zuul 2.2.6.RELEASE and below may be vulnerable to bypassing the “Sensitive Headers” restriction when executing requests with specially constructed URLs. Applications that use Spring Security's StrictHttpFirewall (enabled by default for all URLs) are not affected by the vulnerability, as they reject requests that allow bypassing.Show less

Opencast is a free, open-source platform to support the management of educational audio and video content. In Opencast before version 9.2 there is a vulnerability in which publishing an episode with strict access rules will overwrite the currently set series access. This allows for an easy denial of access for all users without superuser privileges, effectively hiding the series. Access to series and series metadata on the search service (shown in media module and player) depends on the events published which are part of the series. Publishing an event will automatically publish a series and update access to it. Removing an event or republishing the event should do the same. Affected versions of Opencast may not update the series access or remove a published series if an event is being removed. On removal of an episode, this may lead to an access control list for series metadata with broader access rules than the merged access rules of all remaining events, or the series metadata still being available although all episodes of that series have been removed. This problem is fixed in Opencast 9.2.Show less

NeDi 1.9C allows an authenticated user to inject PHP code in the System Files function on the endpoint /System-Files.php via the txt HTTP POST parameter. This allows an attacker to obtain access to the operating system where NeDi is installed and to all application data.Show less

A flaw was found in podman before 1.7.0. File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It does not allow to directly escape the container, though being a privileged container means that a lot of security features are disabled when running the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.Show less

Electric Coin Company Zcashd before 2.1.1-1 allows attackers to trigger consensus failure and double spending. A valid chain could be incorrectly rejected because timestamp requirements on block headers were not properly enforced.Show less

This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of NETGEAR R7450 1.2.0.62_1.0.1 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SOAP API endpoint, which listens on TCP port 80 by default. The issue results from the lack of proper access control. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-11559.Show less

An issue was discovered in rcp in MIT krb5-appl through 1.0.3. Due to the rcp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the rcp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious rcp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rcp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). This issue is similar to CVE-2019-6111 and CVE-2019-7283. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8.Show less

AVideo Platform is an open-source Audio and Video platform. It is similar to a self-hosted YouTube. In AVideo Platform before version 10.2 there is an authorization bypass vulnerability which enables an ordinary user to get admin control. This is fixed in version 10.2. All queries now remove the pass hash and the recoverPass hash.Show less

Polr is an open source URL shortener. in Polr before version 2.3.0, a vulnerability in the setup process allows attackers to gain admin access to site instances, even if they do not possess an existing account. This vulnerability exists regardless of users' settings. If an attacker crafts a request with specific cookie headers to the /setup/finish endpoint, they may be able to obtain admin privileges on the instance. This is caused by a loose comparison (==) in SetupController that is susceptible to attack. The project has been patched to ensure that a strict comparison (===) is used to verify the setup key, and that /setup/finish verifies that no users table exists before performing any migrations or provisioning any new accounts. This is fixed in version 2.3.0. Users can patch this vulnerability without upgrading by adding abort(404) to the very first line of finishSetup in SetupController.php.Show less

An issue was discovered in MantisBT before 2.24.4. Due to insufficient access-level checks, any logged-in user allowed to perform Group Actions can get access to the Summary fields of private Issues via bug_arr[]= in a crafted bug_actiongroup_page.php URL. (The target Issues can have Private view status, or belong to a private Project.)Show less
