Vulnerability from github – Published: 2026-02-11 18:31 – Updated: 2026-02-12 15:32
VLAI
Details
An issue was discovered in OpenSatKit 2.2.1. The DirName field in the telecommand is provided by the ground segment and must be treated as untrusted input. The program copies DirName into the local buffer DirWithSep using strcpy. The size of this buffer is OS_MAX_PATH_LEN. If the length of DirName is greater than or equal to OS_MAX_PATH_LEN, a stack buffer overflow occurs, overwriting adjacent stack memory. The path length check (FileUtil_AppendPathSep) is performed after the strcpy operation, meaning the validation occurs too late and cannot prevent the overflow.

7.8 (High)

D-Link DAP-2622 DDP Set AG Profile Auth Password Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-2622 routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the DDP service. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-20080.

Details
An issue was discovered in router/upnp/src/ssdp.c in DD-WRT before 45724. An unsafe strcpy in the UPnP handling functionality allows an unauthenticated remote attacker to send a request that would overflow an internal fixed buffer. Exploitation requires the DD-WRT user to enable UPnP (which is off by default, and only listens on internal interfaces by default). This occurs in ssdp_msearch (reachable by an M-SEARCH request).

Details
Millenium MP3 Studio versions up to and including 2.0 is vulnerable to a stack-based buffer overflow when parsing .pls playlist files. The application fails to properly validate the length of the File1 field within the playlist, allowing an attacker to craft a malicious .pls file that overwrites the Structured Exception Handler (SEH) and executes arbitrary code. Exploitation requires the victim to open the file locally, though remote execution may be possible if the .pls extension is registered to the application and opened via a browser.

Mitigation MIT-10
Operation
Build and Compilation
Strategy: Environment Hardening
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking.
- D3-SFCV (Stack Frame Canary Validation) from D3FEND [REF-1334] discusses canary-based detection in detail.
Mitigation
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Implementation
Implement and perform bounds checking on input.
Mitigation
Implementation
Do not use dangerous functions such as gets. Use safer, equivalent functions which check for boundary errors.

Build and Compilation
Strategy: Environment Hardening
- Run or compile the software using features or extensions that randomly arrange the positions of a program's executable and libraries in memory. Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.
- Examples include Address Space Layout Randomization (ASLR) [REF-58] [REF-60] and Position-Independent Executables (PIE) [REF-64]. Imported modules may be similarly realigned if their default memory addresses conflict with other modules, in a process known as "rebasing" (for Windows) and "prelinking" (for Linux) [REF-1332] using randomly generated addresses. ASLR for libraries cannot be used in conjunction with prelink since it would require relocating the libraries at run-time, defeating the whole purpose of prelinking.
- For more information on these techniques see D3-SAOR (Segment Address Offset Randomization) from D3FEND [REF-1335].
