Vulnerability Details

CVEID:CVE-2022-30630
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Glob in io/fs due to stack exhaustion. By sending a specially-crafted request using a path which contains a large number of path separators, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233143 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-30635
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Decoder.Decode in encoding/gob due to stack exhaustion. By sending a specially-crafted message containing deeply nested structures, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233147 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-32148
**DESCRIPTION:**Golang Go could allow a remote attacker to obtain sensitive information, caused by improper exposure of client IP addresses in net/http. By calling httputil.ReverseProxy.ServeHTTP with a Request.Header map containing a nil value for the X-Forwarded-For header, an attacker could exploit this vulnerability to obtain the client IP address information, and use this information to launch further attacks against the affected system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233148 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-30631
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Reader.Read in compress/gzip due to stack exhaustion. By parsing a specially-crafted compressed file, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233144 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-30632
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Glob in path/filepath due to stack exhaustion. By sending a specially-crafted request using a path containing a large number of path separators, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233145 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-32189
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw in Float.GobDecode and Rat GobDecode in math/big. By sending a specially-crafted message, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233149 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-28131
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Decoder.Skip in encoding/xml due to stack exhaustion. By parsing a specially-crafted XML document, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233141 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-30633
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Unmarshal in encoding/xml due to stack exhaustion. By parsing a specially-crafted XML document, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233146 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-1705
**DESCRIPTION:**Golang Go is vulnerable to HTTP request smuggling, caused by a flaw with accepting of some invalid Transfer-Encoding headers in the HTTP/1 client in net/http. By sending a specially-crafted HTTP(S) transfer-encoding request header, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233258 for the current score.
