Directory traversal vulnerability in NeroNET 1.2.0.2 and earlier allows remote attackers to read arbitrary files with certain file extensions (such as ZIP, AVI, JPG, TXT, and HTML) via ".." and hex-encoded (1) slash "/" ("%2f") or (2) backslash "\" ("%5c") sequences.

Multiple off-by-one errors in NMMediaServerService.dll in Nero MediaHome 4.5.8.0 and earlier allow remote attackers to cause a denial of service (crash) via a long string in the (1) request line or (2) HTTP Referer header to TCP port 54444, which triggers a heap-based buffer overflow.

Nero MediaHome 4.5.8.0 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an HTTP header without a name.

Nero 7.10.1.0 has an unquoted BINARY_PATH_NAME for NBService, exploitable via a Trojan horse Nero.exe file in the %PROGRAMFILES(x86)%\Nero directory.

Nero BackItUp in the Nero Productline is vulnerable to a path parsing/UI rendering flaw (CWE-22) that, in combination with Windows ShellExecuteW fallback extension resolution, leads to arbitrary code execution when a user clicks a crafted entry. By creating a trailing-dot folder and placing a same-basename script, Nero BackItUp renders the file as a folder icon and then invokes ShellExecuteW, which executes the script via PATHEXT fallback (.COM/.EXE/.BAT/.CMD). The issue affects recent Nero BackItUp product lines (2019-2025 and earlier) and has been acknowledged by the vendor.
