CVE-2006-6171
HighSummary
ProFTPD w wersji 1.3.0a i wcześniejszych nieprawidłowo ustawia limit rozmiaru bufora, gdy w pliku konfiguracyjnym określono CommandBufferSize, co prowadzi do błędu bufora o dwa bajty. Deweloperzy ProFTPD kwestionują tę podatność, twierdząc, że odpowiednia lokalizacja pamięci jest nadpisywana przed dalszym użyciem w dotkniętej funkcji.
Risk Assessment
Podatność ta może prowadzić do nieprzewidzianego zachowania serwera FTP, co może skutkować utratą danych lub nieautoryzowanym dostępem. Jednakże, ze względu na kontrowersje dotyczące jej istnienia, ryzyko może być ograniczone.
Recommendation
Zaleca się monitorowanie aktualizacji ProFTPD oraz stosowanie najnowszych wersji oprogramowania, aby zminimalizować potencjalne ryzyko związane z tą podatnością.

Cocos AI in version 0.8.2 and earlier accepts trusted execution environment attestation Evidence when firmware patch levels and software measurements match, without binding the Evidence to an allowed platform owner or unique machine identity and without enforcing revocation. A remote attacker who controls or compromises another platform trusted by the same verifier can substitute valid Evidence from that platform and cause authorization of the wrong platform. The vulnerability is addressed in 0.9.0, but cannot be patched in source code alone since it arises from the confidential computing threat model itself.
- CVE-2026-83542Critical
A Code Injection vulnerability in Apache OFBiz 24.09 before 24.09.08 allows a remote unauthenticated attacker to execute arbitrary code on the server by staging crafted widget XML in a multipart upload and overriding mainDecoratorLocation, causing evaluation of an unsandboxed Groovy expression.
- CVE-2026-117691Critical
A flaw was found in the SAML HTTP-Redirect binding implementation of Keycloak. The issue occurs because the server processes percent-encoded parameter names (like %53AMLResponse) while the signature verification logic only checks literal parameter names. An attacker can use this discrepancy to provide a crafted, unsigned SAML message that the server processes instead of a legitimately signed one, leading to full account takeover of federated users.
- CVE-2026-96677Critical
Cross-site Scripting (XSS) vulnerability in Apache Juneau. HTML document serialization does not HTML-encode variable substitutions in page chrome fields (header, nav, footer, etc.), so applications that place request-derived values there reflect them unencoded.
- CVE-2026-73117Critical
HTTP Response Splitting (CRLF injection in HTTP headers) vulnerability in Apache Juneau. The REST server passed response header values and redirect targets to the servlet container unchecked, so request-derived data could allow header injection or redirect to an arbitrary site.
- CVE-2026-73116Critical
Insufficiently Protected Credentials vulnerability in Apache Juneau. The RestClient followed HTTP redirects while keeping credential headers from the original request, so a server redirecting to a different host, port, or from HTTPS to HTTP could receive Authorization, Cookie, Proxy-Authorization and X-API-Key headers.
- CVE-2026-73101Critical
Generation of Error Message Containing Sensitive Information vulnerability in Apache Juneau. The REST server sends the internal exception class and message to clients in a "Thrown" response header on every error response and may include internal exception messages in the error body, even with stack-trace rendering disabled.
- CVE-2026-73100Critical
Insertion of Sensitive Information into Log File vulnerability in Apache Juneau. The default REST server call logger records request headers for requests ending in a server error without redaction, so Authorization, Cookie, Proxy-Authorization and X-API-Key headers are written in cleartext to the application log.
- CVE-2026-73099Critical
Cross-Site Request Forgery (CSRF) vulnerability in Apache Juneau. The REST server accepts a "content" query parameter that replaces the request body and is enabled by default on every HTTP method including GET, so a cross-site link can deliver an attacker-chosen request body without a CORS preflight.
- CVE-2026-73098Critical
Improper control of dynamically-loaded code vulnerability in Apache Juneau. When parsing a value into a property of type java.lang.Class, the default class swap loaded the named class with initialization enabled, so input naming a class on the application classpath ran that class's static initializer.
Original NVD description (English source)
ProFTPD 1.3.0a and earlier does not properly set the buffer size limit when CommandBufferSize is specified in the configuration file, which leads to an off-by-two buffer underflow. NOTE: in November 2006, the role of CommandBufferSize was originally associated with CVE-2006-5815, but this was an error stemming from a vague initial disclosure. NOTE: ProFTPD developers dispute this issue, saying that the relevant memory location is overwritten by assignment before further use within the affected function, so this is not a vulnerability
