Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2021-37136)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in Bzip2 decompression decoder function. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Improper input validation (CVE-ID: CVE-2021-37137)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the Content Acquisition System (Netty) component in Oracle Commerce Guided Search. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.
3) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-43797)
The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests when processing control chars present at the beginning / end of the header name. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
4) Infinite loop (CVE-ID: CVE-2022-41881)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the HaProxyMessageDecoder when parsing a TLV with type of "PP2_TYPE_SSL". A remote attacker can pass a specially crafted message to consume all available system resources and cause denial of service conditions.
5) HTTP response splitting (CVE-ID: CVE-2022-41915)
The vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not validate header values when calling DefaultHttpHeaders.set with an iterator of values. A remote attacker can inject arbitrary header values and perform HTTP splitting attacks.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.
