Sam naprawiam lampę insektobójczą Blaupunkt BP-GIK04

Kupiłem lampę insektobójczą Blaupunkt BP-GIK04. I to był błąd. LED INSECT KILLER BP-GIK04 z LED łączy tylko nazwa. Urządzenie wyposażone jest w świetlówkę kompaktową UV. Wyprodukowane zostało w PRC z kilku kawałków tworzywa sztucznego oraz kliku niezbyt solidnie połączonych kabelków. Niestety nie działało. Za pierwszym razem, w dostarczonym urządzeniu działał tylko wentylator. Zostało ono wymienione przez sprzedawcę na kolejne, równie niedziałające urządzenie. W drugim egzemplarzu nie działała ani świetlówka, ani wentylator.

diag_tool.cgi on DASAN H660RM devices with firmware 1.03-0022 allows spawning ping processes without any authorization leading to information disclosure and DoS attacks

diag_tool.cgi on DASAN H660RM devices with firmware 1.03-0022 allows spawning ping processes without any authorization leading to device enumeration on LAN interface and DoS attacks against both device and network.

CWE-862: Missing Authorization weakness in diag_tool.cgi allows remote attacker to spawn ping (and traceroute) processes on affected devices without authorization. Moreover similar bug in diag_get_result.cgi allows attacker to retrieve command output. Arbitrary command injection using ; or ` (back ticks) does not seems to work (which make this different than CVE-2018-10561 and CVE-2018-17869).

This vulnerability was assigned CVE-2019-9974.

Boa Webserver on DASAN H660RM devices with firmware 1.03-0022 saves post data, including credentials, to /tmp/boa-temp

Boa Webserver on DASAN H660RM devices with firmware 1.03-0022 (and possibly other) saves post data, including credentials, to /tmp/boa-temp. Moreover this file is not sanitized after request has been processed, which allow retrieval of login credential possible until another POST request is made.

This vulnerability was assigned CVE-2019-9976.

syslog_tool.cgi on DASAN H660RM devices with firmware 1.03-0022 uses a hard-coded key for logs encryption

DASAN H660RM devices with firmware 1.03-0022 (and possibly other) uses a hard-coded key “dasanektks123” for logs encryption. Data stored using this key can be decrypted by anyone able to access this key.

This vulnerability was assigned CVE-2019-9975.

nCipher HSM with OpenSSL

I just finished playing with some nCipher’s HSM. Unfortunately there is no integration guide for OpenSSL that cover CHIL interface and nCipher hardware security modules.

nCipher’s installation guide is quite good, but after you finish installing hardware, drivers and daemons, you are on your own.

I found only two helpful sources: Andrea Campi’s blog entry about nCipher NetHSM and OpenSSL and Marek Marcola’s post on openssl-users mailing list.

Both guides ends on key generation and self-signed certificates. Its enough to get CHIL enabled application to work with nCipher’s HSM, but will not help you to convert any existing OpenSSL (not an CHIL-aware) application to use HSM.

Virtual destinations are faster than Camel routing

Routing messages from one input queue to two output queues in ActiveMQ can be done in two different ways. Apache Camel, a powerful rule-based routing engine often used with ActiveMQ, is a typical choice. Virtual composite queue is another solution. Which to choose? The faster.
