Stack-based buffer overflow vulnerabilities in the PLANET GS-4210-16P2S managed PoE switch web management interface allow a remote authenticated attacker to crash the CGI process and disrupt web-based device administration. Three separate POST parameter handlers in /cgi-bin/dispatcher.cgi - processing usrPass, enbPass, usrName, and usrPass - copy user-supplied input into fixed-size stack buffers without bounds validation, triggering CWE-121 conditions. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog; impact is confined to denial of service against the web management plane.
Stack-based buffer overflow and null pointer dereference vulnerabilities in the PLANET GS-4210-16P2S managed PoE switch firmware (all versions before 3.441b260626) allow a remote authenticated attacker to crash the CGI-based web management service by submitting crafted POST requests to RADIUS server configuration handlers. The `web_radiusSrv*_post` handler family in `/cgi-bin/dispatcher.cgi` copies user-controlled parameters into fixed-size stack buffers without bounds checking and dereferences `radName`/`radIp` pointers without confirming their presence. No public exploit code exists and the vulnerability is not listed in the CISA KEV catalog at time of analysis; a vendor-released firmware patch is available.
Stack-based buffer overflows in PLANET GS-4210-16P2S managed switch firmware before 3.441b260626 allow a remote administrator to crash the web management interface by sending crafted HTTP POST requests to /cgi-bin/dispatcher.cgi. More than 30 named CGI handler functions - spanning VLAN, SNMP v3, ACL, AAA, DHCP, STP, PoE, and cable diagnostics subsystems - copy attacker-supplied POST parameters into fixed-size stack buffers without length validation. The confirmed impact is denial of service of the web management service; the vulnerability is not listed in CISA KEV and no public exploit code has been identified at time of analysis, though a vendor patch is available.
Null pointer dereference in PLANET GS-4210-16P2S managed switch firmware before 3.441b260626 allows remote authenticated attackers to crash the web management interface by sending a crafted request. The web_poe_alive_rmtip_post handler in /cgi-bin/dispatcher.cgi dereferences the rmtIP POST parameter without first validating its presence, meaning a missing parameter is dereferenced as NULL, faulting the CGI process and rendering the web management interface unavailable. No active exploitation (CISA KEV) or public proof-of-concept has been identified at time of analysis, though the trigger is trivially simple - a single omitted parameter - for any attacker already holding administrative credentials.
Stack buffer overflow in the PLANET GS-4210-16P2S managed switch web management interface exposes all firmware versions prior to 3.441b260626 to unauthenticated remote denial of service and potential memory corruption. The _readHttpParam function copies attacker-supplied HTTP query string data into a fixed-size stack buffer without enforcing size limits or guaranteeing NUL termination, after which parse_query_string processes the unbounded attacker-controlled content. No public exploit code has been identified at time of analysis and KEV status is not confirmed, but the pre-authentication network vector with no special preconditions makes this straightforwardly reachable; a vendor patch is available.
OS command injection in PLANET GS-4210-16P2S managed switch firmware allows a remote attacker with administrator web credentials to execute arbitrary operating-system commands on the device. The web_smtp_test_post handler in /cgi-bin/dispatcher.cgi passes a caller-supplied SMTP server field directly into a shell command without sanitization, exposing the full underlying firmware OS to the authenticated attacker. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis; however, the CVSS 4.0 score of 8.6 reflects full confidentiality, integrity, and availability compromise on successful exploitation.
Authenticated OS command injection in PLANET GS-4210-16P2S managed switch firmware prior to 3.441b260626 enables a remote administrator to execute arbitrary commands on the device operating system via a crafted certificate upload request targeting /cgi-bin/httpuploadcert.cgi. The certificate password field is incorporated into a shell command without sanitization of shell metacharacters, a textbook CWE-78 root cause. No public exploit code or CISA KEV listing has been identified at time of analysis; exploitation requires valid administrator-level web credentials, confirmed by CVSS 4.0 PR:H.
OS command injection in the PLANET GS-4210-16P2S managed PoE switch firmware before 3.441b260626 allows an authenticated remote attacker with administrative access to execute arbitrary operating-system commands on the device. The VLAN membership editing handler in /cgi-bin/dispatcher.cgi passes the memberTags POST parameter directly into a shell command without any sanitization, constituting a textbook CWE-78 flaw. No public exploit code and no CISA KEV listing are identified at time of analysis, though the CVSS 4.0 score of 8.6 reflects full confidentiality, integrity, and availability impact upon successful exploitation.
