Debian Linux Security Advisory 5455-1 - A memory allocation issue was found in iperf3, the Internet Protocol bandwidth measuring tool, that may cause denial of service when encountering certain invalid length value in TCP packet.

An issue was discovered in the Linux kernel before 6.3.9. ksmbd does not validate the SMB request protocol ID, leading to an out-of-bounds read.

Progress Chef Infra Server before 15.7 allows a local attacker to exploit a /var/opt/opscode/local-mode-cache/backup world-readable temporary backup path to access sensitive information, resulting in the disclosure of all indexed node data, because OpenSearch credentials are exposed. (The data typically includes credentials for additional systems.) The attacker must wait for an admin to run the "chef-server-ctl reconfigure" command.

Debian Linux Security Advisory 5454-1 - Riccardo Bonafede discovered that the Kanboard project management software was susceptible to SQL injection.

Debian Linux Security Advisory 5453-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

Debian Linux Security Advisory 5452-1 - Multiple security issues were discovered in the GPAC multimedia framework which could result in denial of service or the execution of arbitrary code.

netkit-rcp in rsh-client 0.17-24 allows command injection via filenames because /bin/sh is used by susystem, a related issue to CVE-2006-0225, CVE-2019-7283, and CVE-2020-15778.

### Summary Path traversal vulnerability detected in .cpr subfolder. The Path Traversal attack technique allows an attacker access to files, directories, and commands that reside outside the web document root directory. Tested in Debian Linux. ### Details Steps to reproduce: 1)Install the software python3 -m pip install --user -U copyparty 2)Execute using the default config : copyparty 3) Execute the POC curl command 4) /etc/passwd file of the remote server is accessible. ### PoC ```bash curl -i -s -k -X GET 'http://172.19.1.2:3923/.cpr/%2Fetc%2Fpasswd' ``` Additional examples: http://172.19.4.2:3923/.cpr/a/..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2Fetc%2Fpasswd http://172.19.4.2:3923/.cpr/deps/..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2Fetc%2Fpasswd ### Checking for exposure if copyparty is running behind a reverse proxy, you can check the access-logs for traces of attacks, by grepping your access...

### Impact Attacker could modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g. when the user views a file containing the malicious sequence, which could allow the attacker to execute arbitrary commands. ### Credit These bugs were found and disclosed by David Leadbeater <[email protected]> (@dgl at Github.com) ### Patches Fixed in version ce596e0dc8cdb288bc7ed5c6a59011ee3a8dc171 ### Workarounds There are no workarounds available ### References Similar exploits to this existed in the past, for terminal emulators: https://nvd.nist.gov/vuln/detail/CVE-2003-0063 https://nvd.nist.gov/vuln/detail/CVE-2008-2383 Additional background and information is also available: https://marc.info/?l=bugtraq&m=104612710031920&w=2 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=510030

Copyparty is a portable file server. Versions prior to 1.8.2 are subject to a path traversal vulnerability detected in the `.cpr` subfolder. The Path Traversal attack technique allows an attacker access to files, directories, and commands that reside outside the web document root directory. This issue has been addressed in commit `043e3c7d` which has been included in release 1.8.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.
