Detailsinfo

A vulnerability classified as critical has been found in D-Link DIR-882 FW102B02. This affects the function sub_433188 of the file prog.cgi of the component HTTP Handler. The manipulation of the argument EmailFrom/EmailTo/SMTPServerAddress/SMTPServerPort/AccountName with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1_FW102B02 within the `prog.cgi` and `rc` binaries. The `sub_433188` function in `prog.cgi` stores user-supplied email configuration parameters (`EmailFrom`, `EmailTo`, `SMTPServerAddress`, `SMTPServerPort`, `AccountName`) in NVRAM via `nvram_safe_set`. These values are later retrieved in the `sub_448FDC` function of `rc` using `nvram_safe_get` and concatenated into shell commands executed via `twsystem()` without sanitization. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device through specially crafted HTTP requests to the router's web interface.

The advisory is shared at dlink.com. This vulnerability is uniquely identified as CVE-2025-60701 since 09/26/2025. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 11/13/2025). MITRE ATT&CK project uses the attack technique T1202 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
