Low risk25th percentile - higher than 25% of all known CVEs
Summary
Podatność w goshs, prostym serwerze HTTP napisanym w Go, występuje w wersjach od 1.0.7 do przed 2.0.0-beta.4. Komenda SFTP 'rename' sanitizuje jedynie ścieżkę źródłową, co pozwala na zapis poza katalogiem głównym SFTP.
Risk Assessment
Organizacje mogą być narażone na nieautoryzowany dostęp do systemów plików, co może prowadzić do wycieku danych lub modyfikacji plików. Wykorzystanie tej podatności może zagrażać integralności i poufności danych.
Recommendation
Zaleca się aktualizację do wersji 2.0.0-beta.4 lub nowszej, aby usunąć tę podatność. Należy również przeprowadzić audyt konfiguracji SFTP w celu zapewnienia bezpieczeństwa.

Buffer overflow in the data receiving process in NEC WebSAM WinShare versions 7.5.0 and earlier, 7.6.0, and 7.7.0 through 7.7.2 on Windows allows a remote unauthenticated attacker to execute arbitrary code with SYSTEM privileges via a crafted packet with a malformed data size value in the protocol header.
Original NVD description (English source)
goshs is a SimpleHTTPServer written in Go. From 1.0.7 to before 2.0.0-beta.4, the SFTP command rename sanitizes only the source path and not the destination, so it is possible to write outside of the root directory of the SFTP. This vulnerability is fixed in 2.0.0-beta.4.
