CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-32040 – Large aggregation pipelines with a specific stage can crash mongod under default configuration
https://notcve.org/view.php?id=CVE-2021-32040
It may be possible to have an extremely long aggregation pipeline in conjunction with a specific stage/operator and cause a stack overflow due to the size of the stack frames used by that stage. If an attacker could cause such an aggregation to occur, they could maliciously crash MongoDB in a DoS attack. This vulnerability affects MongoDB Server v4.4 versions prior to and including 4.4.28, MongoDB Server v5.0 versions prior to 5.0.4 and MongoDB Server v4.2 versions prior to 4.2.16. Workaround: >= v4.2.16 users and all v4.4 users can add the --setParameter internalPipelineLengthLimit=50 instead of the default 1000 to mongod at startup to prevent a crash. Puede ser posible tener una tubería de agregación extremadamente larga en conjunto con una etapa/operador específico y causar un desbordamiento de pila debido al tamaño de los marcos de pila usados por esa etapa. Si un atacante pudiera causar tal agregación, podría colapsar MongoDB de forma maliciosa en un ataque DoS. • https://jira.mongodb.org/browse/SERVER-58203 https://jira.mongodb.org/browse/SERVER-59299 https://jira.mongodb.org/browse/SERVER-60218 https://security.netapp.com/advisory/ntap-20220609-0005 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 7.1EPSS: 0%CPEs: 3EXPL: 0CVE-2021-32036 – Denial of Service and Data Integrity vulnerability in features command
https://notcve.org/view.php?id=CVE-2021-32036
An authenticated user without any specific authorizations may be able to repeatedly invoke the features command where at a high volume may lead to resource depletion or generate high lock contention. This may result in denial of service and in rare cases could result in id field collisions. This issue affects MongoDB Server v5.0 versions prior to and including 5.0.3; MongoDB Server v4.4 versions prior to and including 4.4.9; MongoDB Server v4.2 versions prior to and including 4.2.16 and MongoDB Server v4.0 versions prior to and including 4.0.28 Un usuario autenticado sin ninguna autorización específica puede ser capaz de invocar repetidamente el comando features donde a un alto volumen puede conllevar a un agotamiento de recursos o generar una alta contención de bloqueos. Esto puede resultar en una denegación de servicio y, en casos raros, podría resultar en colisiones del campo id • https://jira.mongodb.org/browse/SERVER-59294 • CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2021-20330
An attacker with basic CRUD permissions on a replicated collection can run the applyOps command with specially malformed oplog entries, resulting in a potential denial of service on secondaries. This issue affects MongoDB Server v4.0 versions prior to 4.0.27; MongoDB Server v4.2 versions prior to 4.2.16; MongoDB Server v4.4 versions prior to 4.4.9. Un atacante con permisos CRUD básicos en una colección replicada puede ejecutar el comando applyOps con entradas oplog especialmente malformadas, resultando en una potencial denegación de servicio en los secundarios.
