CVE-2025-68274
HighSummary
W bibliotece SIPGO, używanej do pisania usług SIP w języku GO, występuje podatność na dereferencję wskaźnika nil w funkcji `NewResponseFromRequest`. Problem ten dotyczy wszystkich normalnych operacji SIP i pozwala zdalnym atakującym na awarię dowolnej aplikacji SIP poprzez wysłanie jednego źle sformułowanego żądania SIP bez nagłówka To.
Risk Assessment
Podatność ta może prowadzić do zakłócenia działania aplikacji SIP, co wpływa na kluczowe operacje takie jak zestawienie połączeń, uwierzytelnianie i obsługę wiadomości. Wszelkie aplikacje SIP korzystające z biblioteki sipgo są narażone na ten problem.
Recommendation
Zaleca się aktualizację biblioteki SIPGO do wersji 1.0.0-alpha-1, która zawiera poprawkę dla tej podatności, aby zabezpieczyć aplikacje przed potencjalnymi atakami.

- CVE-2026-88857Critical
In the OrdaSoft Joomla Gallery extension for Joomla versions below 6.2.7, an authenticated privileged remote code execution vulnerability was found. The saveWatermark() function copies an uploaded file to a web-accessible directory using the client-supplied filename exactly as sent, with no extension check, content check, or filename sanitization. An authenticated core.manage user could upload a .php file disguised with an image Content-Type header and execute it directly by requesting the resulting path.
- CVE-2026-88856Critical
In the OrdaSoft Joomla Gallery extension for Joomla versions below 6.2.7, an authenticated privileged remote code execution vulnerability was found. The updateOSGallery() function, reached via task=update_osgallery, reads a JSON request body and calls the value of a method field as a live PHP function, passing the value of a package field as its single argument, with no allow-list or is_callable() check. Any function name compatible with a single argument is directly reachable, including system, exec, shell_exec, and passthru.
Original NVD description (English source)
SIPGO is a library for writing SIP services in the GO language. Starting in version 0.3.0 and prior to version 1.0.0-alpha-1, a nil pointer dereference vulnerability is in the SIPGO library's `NewResponseFromRequest` function that affects all normal SIP operations. The vulnerability allows remote attackers to crash any SIP application by sending a single malformed SIP request without a To header. The vulnerability occurs when SIP message parsing succeeds for a request missing the To header, but the response creation code assumes the To header exists without proper nil checks. This affects routine operations like call setup, authentication, and message handling - not just error cases. This vulnerability affects all SIP applications using the sipgo library, not just specific configurations or edge cases, as long as they make use of the `NewResponseFromRequest` function. Version 1.0.0-alpha-1 contains a patch for the issue.
