The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn\u0027t greater than the input buffer. This leads to adjacent memory being decoded as well. An attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the display of usernames on error pages.",

* squid: Improper input validation in URI processor (CVE-2019-12523)
* squid: Improper access restriction in url_regex may lead to security bypass (CVE-2019-12524)
* squid: Heap overflow issue in URN processing (CVE-2019-12526)
* squid: Information Disclosure issue in FTP Gateway (CVE-2019-12528)
* squid: Out of bounds read in Proxy-Authorization header causes DoS (CVE-2019-12529)
* squid: Denial of service in cachemgr.cgi (CVE-2019-12854)
* squid: Buffer overflow in URI processor (CVE-2019-18676)
* squid: Cross-Site Request Forgery issue in HTTP Request processing (CVE-2019-18677)
* squid: HTTP Request Splitting issue in HTTP message processing (CVE-2019-18678)
* squid: Information Disclosure issue in HTTP Digest Authentication (CVE-2019-18679)
* squid: Mishandled HTML in the host parameter to cachemgr.cgi results in insecure behaviour (CVE-2019-18860)
* squid: Improper input validation issues in HTTP Request processing (CVE-2020-8449)
* squid: Buffer overflow in reverse-proxy configurations (CVE-2020-8450)
* squid: DoS in TLS handshake (CVE-2020-14058)
* squid: Request smuggling and poisoning attack against the HTTP cache (CVE-2020-15049)

This decoded info may contain special characters to delimit the domain, and treat the rest of the URL as a path or query string. An attacker could first make a request to their domain using an encoded username, then when a request for the target domain comes in that decodes to the exact URL, it will serve the attacker\u0027s HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows an attacker to gain access to features that only reverse proxies can use, such as ESI.",

When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it\u0027s off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can\u0027t affect adjacent memory blocks, and thus just leads to a crash while processing.",

When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn\u0027t greater than the input buffer. This leads to adjacent memory being decoded as well. An attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the display of usernames on error pages.",

"text": "An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no effects on Squid itself, nor on any upstream servers. The issue is related to a request header containing whitespace between a header name and a colon.",

This decoded info may contain special characters to delimit the domain, and treat the rest of the URL as a path or query string. An attacker could first make a request to their domain using an encoded username, then when a request for the target domain comes in that decodes to the exact URL, it will serve the attacker\u0027s HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows an attacker to gain access to features that only reverse proxies can use, such as ESI.",

When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it\u0027s off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can\u0027t affect adjacent memory blocks, and thus just leads to a crash while processing.",

When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn\u0027t greater than the input buffer. This leads to adjacent memory being decoded as well. An attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the display of usernames on error pages.",

"text": "An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no effects on Squid itself, nor on any upstream servers. The issue is related to a request header containing whitespace between a header name and a colon.",

It does this by making a MD5 hash of the absolute URL of the request. If found, it servers the request. The absolute URL can include the decoded UserInfo (username and password) for certain protocols. This decoded info is prepended to the domain. This allows an attacker to provide a username that has special characters to delimit the domain, and treat the rest of the URL as a path or query string. An attacker could first make a request to their domain using an encoded username, then when a request for the target domain comes in that decodes to the exact URL, it will serve the attacker\u0027s HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows an attacker to gain access to features that only reverse proxies can use, such as ESI.",

It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no effects on Squid itself, nor on any upstream servers. The issue is related to a request header containing whitespace between a header name and a colon.",
