OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.7 and 3.2.4, OpenSIPS crashes when a malformed SDP body is received and is processed by the `delete_sdp_line` function in the sipmsgops module. This issue can be reproduced by calling the function with an SDP body that does not terminate by a line feed (i.e. `\n`). The vulnerability was found while performing black-box fuzzing against an OpenSIPS server running a configuration that made use of the functions…

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Versions prior to 3.1.7 and 3.2.4 have a potential issue in `msg_translator.c:2628` which might lead to a server crash. This issue was found while fuzzing the function `build_res_buf_from_sip_req` but could not be reproduced against a running instance of OpenSIPS. This issue could not be exploited against a running instance of OpenSIPS since no public function was found to make use of this vulnerable code. Even in the case of…
OpenSIPS, a Session Initiation Protocol (SIP) server implementation, has a memory leak starting in the 2.3 branch and priot to versions 3.1.8 and 3.2.5. The memory leak was detected in the function `parse_mi_request` while performing coverage-guided fuzzing. This issue can be reproduced by sending multiple requests of the form `{"jsonrpc": "2.0","method": "log_le`. This malformed message was tested against an instance of OpenSIPS via FIFO transport layer and was found to…
OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.9 and 3.2.6, a malformed SIP message containing a large _Content-Length_ value and a specially crafted Request-URI causes a segmentation fault in OpenSIPS. This issue occurs when a large amount of shared memory using the `-m` flag was allocated to OpenSIPS, such as 10 GB of RAM. On the test system, this issue occurred when shared memory was set to `2362` or higher. This issue is fixed in versions 3.1.9 and 3.2.6.…
OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.7 and 3.2.4, a specially crafted Authorization header causes OpenSIPS to crash or behave in an unexpected way due to a bug in the function `parse_param_name()` . This issue was discovered while performing coverage guided fuzzing of the function parse_msg. The AddressSanitizer identified that the issue occurred in the function `q_memchr()` which is being called by the function `parse_param_name()`. This issue may…
An issue was discovered in GFI Kerio Connect 9.4.1 patch 1 (fixed in 10.0.0). There is a stack-based Buffer Overflow in the webmail component's 2FASetup function via an authenticated request with a long primaryEMailAddress field to the webmail/api/jsonrpc URI.
Broken access control in Advanced Authentication versions prior to 6.4.1.1 and 6.3.7.2
TP-Link Archer AX21 (AX1800) firmware versions before 1.1.4 Build 20230219 contained a command injection vulnerability in the country form of the /cgi-bin/luci;stok=/locale endpoint on the web management interface. Specifically, the country parameter of the write operation was not sanitized before being used in a call to popen(), allowing an unauthenticated attacker to inject commands, which would be run as root, with a simple POST request.
A reflected cross-site scripting vulnerability in the OAuth flow completion endpoints in Mattermost allows an attacker to send AJAX requests on behalf of the victim via sharing a crafted link with a malicious state parameter.
