Vulnerability Details

CVEID:CVE-2023-39410
**DESCRIPTION:**Apache Avro Java SDK could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an unsafe deserialization flaw. By sending specially crafted input, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/267324 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2023-34054
**DESCRIPTION:**VMware Tanzu Reactor Netty is vulnerable to a denial of service, caused by a flaw when built-in integration with Micrometer is enabled. By sending specially crafted HTTP requests, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/272536 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2024-1597
**DESCRIPTION:**PostgreSQL JDBC Driver (PgJDBC) is vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements when using the non-default connection property preferQueryMode=simple in combination with application code that has a vulnerable SQL that negates a parameter value, which could allow the attacker to view, add, modify or delete information in the back-end database.
CVSS Base score: 10
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/283693 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H)

CVEID:CVE-2023-34462
**DESCRIPTION:**Netty is vulnerable to a denial of service, caused by a flaw with allocating up to 16MB of heap for each channel during the TLS handshake the SniHandler class. By sending a specially crafted client hello packet, a remote authenticated attacker could exploit this vulnerability to cause a OutOfMemoryError and so result in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258713 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-34062
**DESCRIPTION:**VMware Tanzu Reactor Netty could allow a remote attacker to traverse directories on the system, caused by improper validation of user request. An attacker could send a specially crafted URL request containing “dot dot” sequences (/…/) to view arbitrary files on the system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/271850 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2023-44487
**DESCRIPTION:**Multiple vendors are vulnerable to a denial of service, caused by a flaw in handling multiplexed streams in the HTTP/2 protocol. By sending numerous HTTP/2 requests and RST_STREAM frames over multiple streams, a remote attacker could exploit this vulnerability to cause a denial of service due to server resource consumption.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268044 for the current score.
